Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 11% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal investment strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the fund invests at least 80% of its net assets, plus borrowings for investment purposes, if any, in equity securities, or other investments with similar economic characteristics, of companies with large market capitalizations.
Risk [Heading]	rr_RiskHeading	Certain risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Risk is inherent in all investing. There is no assurance that the fund will meet its investment objectives. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the fund. Stock market and equity securities risk. The securities markets are volatile and the market prices of the fund's securities may decline generally. Securities fluctuate in price based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the fund fall, the value of your investment in the fund will decline. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts to respond to the crisis, or investor perception that such efforts are not succeeding could also negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and in other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. Issuer risk. The value of a security can go up or down more than the market as a whole and can perform differently from the value of the market as a whole, often due to disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer or changes in government regulations affecting the issuer or the competitive environment. The fund may experience a substantial or complete loss on an individual security. Historically, the prices of securities of small and medium capitalization companies have generally gone up or down more than those of large capitalization companies, although even large capitalization companies may fall out of favor with investors. Large capitalization company risk. Large capitalization companies may fall out of favor with investors. Liquidity risk. Some assets held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid assets may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss. Portfolio selection risk. The value of your investment may decrease if the subadviser's judgment about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements is incorrect. Value investing risk. The value approach to investing involves the risk that stocks may remain undervalued. Value stocks may underperform the overall equity market while the market concentrates on growth stocks. Although the fund will not concentrate its investments in any one industry or industry group, it may, like many value funds, weight its investments toward certain industries, thus increasing its exposure to factors adversely affecting issuers within those industries. Risk of increase in expenses. Your actual costs of investing in the fund may be higher than the expenses shown in "Annual fund operating expenses" for a variety of reasons. For example, expense ratios may be higher than those shown if a fee limitation is changed or terminated or if average net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile. These risks are discussed in more detail later in this Prospectus or in the SAI.
Risk Lose Money [Text]	rr_RiskLoseMoney	You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The accompanying bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Class I shares. The table shows the average annual total returns of each class of the fund that has been in operation for at least one full calendar year and also compares the fund's performance with the average annual total returns of an index or other benchmark. The fund also compares its performance to the S&P 500 Index. Performance for classes other than those shown may vary from the performance shown to the extent the expenses for those classes differ. The fund makes updated performance information available at the fund's website, http://www.leggmason.com/individualinvestors/products/mutual-funds/annualized_performance (select share class), or by calling the fund at 1-877-721-1926. The fund’s past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. Sales charges are not reflected in the accompanying bar chart, and if those charges were included, returns would be less than those shown.

[1] Generally,

[2] If your shares are held in a direct account and the value of your account is below $1,000 ($250 for retirement plans that are not employer-sponsored), the fund may charge you a fee of $3.75 per account that is determined and assessed quarterly (with an annual maximum of $15.00 per account). Direct accounts generally include accounts held in the name of the individual investor on the fund's books and records.

[3] "Other expenses" are estimated for the current fiscal year. Actual expenses may differ from estimates.

[4] N/A

[5] The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses) so that total annual operating expenses are not expected to exceed 1.42% for Class A2 shares, 1.20% for Class FI shares, 1.45% for Class R shares and 0.90% for Class I shares. In addition, total annual fund operating expenses for Class IS shares and Class 1 shares will not exceed total annual fund operating expenses for Class I shares and Class A shares, respectively. These arrangements cannot be terminated prior to December 31, 2014 without the Board of Trustees' consent. The manager is permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class' total annual operating expenses have fallen to a level below the limits described above.
