Photoalignment materials and liquid crystal display device and method for fabricating the same with said materials

摘要

Polyamideimide photoalignment materials having a photosensitive diamine derivative compound with side branches, and liquid crystal display devices using such a photoalignment material, beneficially as an alignment film. A liquid crystal display device includes a first substrate with such a photoalignment material. The polyamideimide photoalignment materials have a chemical structure as follows:
