Thermosetting liquid crystal composition having photo-alighment property, alignment and retardation film and method for producing the same, retardation plate and method for producing the same, optical member and method for producing the same, and a display device

Abstract

Provided is a thermosetting liquid crystal composition having photo-alignment property, the composition comprising a side-chain liquid crystal polymer (A) which comprises a liquid crystalline constitutional unit including a liquid crystalline moiety in a side chain thereof and a non-liquid crystalline constitutional unit including an alkylene group in a side chain thereof, a copolymer (B) which comprises a photo-alignment constitutional unit including a photo-alignment group in a side chain thereof and a thermally crosslinkable constitutional unit including a thermally crosslinkable group in a side chain thereof and in which the photo-alignment constitutional unit does not include a linear alkylene group between the photo-alignment group and a monomer unit, and a thermal crosslinking agent (C) which is bound to the thermally crosslinkable group of the thermally crosslinkable constitutional unit.
