The present invention addresses the problems of providing an optical film (phase difference film) that exhibits superior anti-reflection functionality not only in a direction perpendicular to the film, but also at wide angles, providing an optical film which continues to exhibit this functionality even after being exposed to high temperature conditions, and providing an elliptical polarizing plate and a display device using these optical films. The present invention provides an optical film having a first phase difference layer and a second phase difference layer. The first phase difference layer is formed from a cured product of a polymerizable composition comprising: at least one or more types of a compound A having three or more polymerizable groups and satisfying (formula 1); and at least one or more types of a compound B satisfying (formula 2). The second phase difference layer is formed from a cured product of a polymerizable composition comprising at least one or more types of a compound satisfying the (formula 1) and/or the compound B satisfying the (formula 2).
