Abstract
Photoalignment of liquid crystals is evaluated as a method of achieving patterned alignment for vertically aligned LCDs suitable for LCTV and other applications. The performance of photoalignment is demonstrated to be equivalent to rubbed alignment, with the considerable advantage of easy patterning of the alignment direction. Photoalignment is found currently to have some limitation on its long-term stability, however schemes for overcoming this limitation are discussed.
