摘要：

Liquid-crystal (LC) photoalignment using azo dyes is described. It will be shown that this photoaligning method can provide a highly uniform alignment with a controllable pretilt angle and strong anchoring energy of the LC cell, as well as a high thermal and UV stability. The application of LC photoalignment to the fabrication of various types of liquid-crystal displays, such as VAN-LCDs, FLCDs, TN-LCDs, and microdisplays, on glass and plastic substrates is also discussed. Azo-dye photo-aligned super-thin polarizers and phase retarders are considered as new optical elements in LCD production, in particular for transflective displays.
