Liquid crystal display device for use as monitors for e.g. notebook computers, has alignment layer formed of polymeric material containing a polymer main chain and photoreaction group, and liquid crystal layer between two substrates

摘要

A liquid crystal display device comprises two substrates (100, 200), alignment layer (300a, 300b) formed on the substrate(s); and liquid crystal layer (400) between the substrates. The alignment layer is formed of polymeric material containing a polymer main chain and photoreaction group combined with the polymer main chain that generates a photo-dimerization reaction by UV rays. An independent claim is included for a method of fabricating an LCD device, comprising coating an alignment layer on the substrates; rubbing the alignment layer; and irradiating polarized UV rays onto the alignment layer, where the alignment layer is formed of a polymeric material containing a polymer main chain and a photoreaction group combined with the polymer main chain that generates a photo-dimerization reaction by UV rays.
