| description | The present invention addresses the problem of providing an optical film, an optical laminate, and an image display device which, when applied to a self-emission type image display device using an inorganic EL element, an organic EL element, or the like, can obtain an image display device that has both an anti-reflection effect of external light and an improved utilization efficiency of light emitted by a light-emitting element. The optical film according to the present invention has a light-absorbing anisotropic film formed from a cured product of a liquid crystal composition containing a polymerizable liquid crystal compound and a dichroic dye compound, the light-absorbing anisotropic film has, in the same film surface, a region A inclined with respect to the absorption axis of the film surface as [theta] A and a region B inclined with respect to the absorption axis of the film surface as [theta] B, and [theta] A and [theta] B satisfy the relationships of the following expressions (1) and (2): [theta] A-[th |
