Abstract
Cinnamate-containing photopolymers for use in liquid crystal display are provided. The photopolymers can be homopolymers or copolymers, and have improved thermostability and photoelectric characteristics. The photopolymers contain a substituted benzene ring and have a weight average molecular weight of from about 1000 to about 100,000. Methods for forming LCD cells using the cinnamate-containing homopolymers and copolymers are also provided.
