Abstract
A liquid crystal photoalignment agent is provided. The liquid crystal photoalignment agent is a copolymer of a cyclobutane dianhydride (“CBDA”) and a CBDA derivative.
Claims20
A liquid crystal photoalignment agent comprising:
- a copolymer of a cyclobutane dianhydride and a cyclobutane dianhydride derivative.
A liquid crystal display comprising:
- a first substrate;
- a thin film transistor disposed on the first substrate;
- a first electrode connected to the thin film transistor;
- and
- a first alignment layer disposed on the first electrode,
- wherein the first alignment layer comprises a liquid crystal photoalignment agent comprising a copolymer of a cyclobutane dianhydride and a cyclobutane dianhydride derivative.
