PHOTOALIGNMENT AGENT OF LIQUID CRYSTAL, PHOTOALIGNMENT FILM OF LIQUID CRYSTAL INCLUDING THE SAME, AND LIQUID CRYSTAL DISPLAY INCLUDING THE SAME

摘要

A photoalignment agent is provided to ensure excellent reliability relating to after image and excellent liquid crystal orientation, to stabilize vertical alignment power and to secure stability to the change of a processing condition. A photoalignment agent, comprises based on solid portion, a polysiloxanepolymer 10-99.9 weight% and a polyimide photopolymer 0.1-90 weight% represented by chemical formula 4. The polyorgansiloxane polymer is obtained by polymerizing any one alkoxysilane compound selected from the group consisting of compounds represented by chemical formula 1: Si(R1)4, chemical formula 2: Si(R2)4, chemical formula 3: (R4)3Si-(R3)n-Si(R4)3, and combinations thereof. The solid portion of the photoalignment agent is 1-30 weight%.
