Abstract: The present invention provides a liquid crystal film having an optically anisotropic layer having excellent alignment and excellent adhesiveness. The present invention further provides an optical laminate, a circularly polarizing plate, and an organic EL display device, each of which uses the optically anisotropic layer. The liquid crystal film of an embodiment of the present invention is a liquid crystal film having at least an optically anisotropic layer formed with a liquid crystal composition including a polymerizable liquid crystal compound and a fluoroaliphatic group-containing copolymer, and a support, in which the fluoroaliphatic group-containing copolymer has a repeating unit derived from a fluoroaliphatic group-containing monomer represented by General Formula (1) and a repeating unit having a polymerizable group polymerizable with the polymerizable liquid crystal compound.

Abstract: An object of the present invention is to provide a photo-alignable polymer which has excellent coating properties, is capable of suppressing film thickness unevenness, and has excellent upper layer coating properties and good liquid crystal alignment properties after being formed as a layer; a binder composition; a binder layer; an optical laminate; a method for producing an optical laminate; and an image display device. The photo-alignable polymer of an embodiment of the present invention is a photo-alignable polymer having a repeating unit A including a cleavage group capable of decomposing by an action of at least one selected from the group consisting of light, heat, an acid, and a base to generate a polar group, in which the repeating unit A has the cleavage group in a side chain, has a fluorine atom or a silicon atom on a side closer to a terminal than the cleavage group in the side chain, and the photo-alignable polymer satisfies Condition 1 or Condition 2 shown below.
Condition 1: The photo-alignable polymer further has a repeating unit B including a photo-alignable group, in addition to the repeating unit A.
Condition 2: The repeating unit A includes a photo-alignable group on a side closer to the main chain than the cleavage group in the side chain.
