Abstract
Provided is an optical film and an optical laminate that achieve an image display device capable of an antireflection effect of external light and improvement of utilization efficiency of light emitted by a light emitting element when applied to a self-emission type image display device formed of an inorganic EL element, an organic EL element, or the like. The optical film includes a light absorption anisotropic film consisting of a cured substance of a liquid crystal composition that contains a polymerizable liquid crystal compound and a dichroic coloring agent compound, in which the light absorption anisotropic film has, in the same film surface, regions A and B where an inclination of an absorption axis with respect to a film surface is θA and θB, respectively, and θA and θB satisfy relationships of Expressions (1) |θA−θB|≥10° and (2) 0°≤θB≤5°.
