LIQUID CRYSTAL ALIGNMENT FILM, METHOD OF PRODUCING THE SAME, LIQUID CRYSTAL DISPLAY MADE BY USING THE FILM, AND METHOD OF PRODUCING THE SAME

摘要

A liquid crystal alignment film comprising a molecule group with one end thereof chemically adsorbed on the surface of a substrate, wherein the molecule group contains molecules each having a linear carbon chain and at least part of the linear carbon chains are selectively polymerized, thus suppressing the panel having a large area and the substrate surface having a stepped portion from losing the uniformity of alignment. Since the liquid crystals are aligned without resort to any physical contact means such as rubbing, an increased area of the panel and the stepped portion on the surface of the substrate do not basically affect the uniformity of alignment. Since the liquid crystal alignment film is chemically adsorbed on the surface of the substrate, the film exhibits excellent properties in the durability of the film, such as resistance against peeling.
