Abstract

See full text

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.
