Abstract

A cured-film formation composition that forms a cured film exhibiting excellent liquid-crystal orientation properties and excellent light transmission properties when the cured-film formation composition is used as an orientation material and a layer of a polymerizable liquid crystal is arranged thereon. A cured-film formation composition including a component (A) that is a compound obtained by reacting a cinnamic acid compound of Formula (1) below with a compound having at least one epoxy group in one molecule, wherein R, R, R, R, and Rare each independently a substituent selected from a hydrogen atom, a halogen atom, a Calkyl, a Chaloalkyl, a Calkoxy, a Chaloalkoxy, cyano, and nitro; and a component (B) that is a cross-linking agent, an orientation material which is obtained from the composition, and a retardation material which is obtained from the composition.
