| Abstract: | A photo sensitive polyimide was synthesized and its chemical property was studied. Its aligning effect on MLC LC2000 was investigated and the aligning direction was examined by coupling with rubbed PI to form LCD cell. The photo generated pretilt angle increases with increasing the incident angle of polarized UV light irradiation. The photo alignment material also shows excellent heat resistance. |
