Abstract

A cured-film formation composition that includes: (A) one or more compounds having a photo-aligning group and hydroxy group, etc.; (B) a polymer having at least one substituent from the group of a hydroxy group, carboxy group, amino group, and alkoxysilyl group, and the like; and (C) a cross-linking agent. Component (A) contains a compound having a group of Formula [1] below as the photo-aligning group: where Aand Aare independently a hydrogen atom or methyl group; and Ais a hydroxy group. A cured-film is formed from the cured-film formation composition, and orientation material is formed by use of photo-alignment technique. A retardation material is obtained by applying a polymerizable liquid crystal on the orientation material and curing it.
