Title:
HOMEOTROPICALLY ORIENTED LIQUID-CRYSTAL FILM, OPTICAL FILM COMPRISING THE SAME, AND IMAGE DISPLAY
Document Type and Number:
WIPO Patent Application WO/2006/085454
Kind Code:
A1
Abstract:
On an alignment substrate, a liquid-crystalline substance comprising as a constituent ingredient a side-chain type liquid-crystalline polymer having an oxetanyl group is homeotropically oriented in a liquid-crystalline state. Thereafter, the oxetanyl group is reacted to fix the homeotropic orientation. Thus, a homeotropically oriented liquid-crystal film can be stably produced without necessitating a complicated step such as light irradiation in an inert gas atmosphere. The film is excellent in orientation retention after homeotropic orientation fixing and in mechanical strength.
