PHOTOALIGNMENT AGENT, PHOTOALIGNMENT LAYER, LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD OF MANUFACTURING THE SAME

摘要

A liquid crystal display device is provided. An exemplary embodiment of the present invention provides a liquid crystal display device including: 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. The first alignment layer includes: a copolymer formed from at least one compound of cyclobutane dianhydride (CBDA) and a cyclobutane dianhydride derivative, and a first diaminean including alkylene group (—CkH2k−, k being a natural number); and a cross-linking agent including an alkylene group (—CnH2n−, n being a natural number), wherein the copolymer includes polyimide.
