Alignment Film Material and Corresponding Liquid Crystal Panel

摘要

The present invention provides an alignment film material, which is used for a liquid crystal display with polymer stabilized vertical alignment, it comprises: a polymer, an oligomer, and a solvent, wherein, the polymer and/or the oligomer comprise group structures of the benzophenone and methyl acrylate. Accordingly, the present invention also provides a liquid crystal panel using the above alignment film. The embodiments according to the present invention regulates the reaction rate of the polymerizable monomer and the polymerizable monomer residues in the polymer stabilized vertical alignment crystal mixture using the alignment film material, which controls the contents of the movable ion in the liquid crystal panel, in order to improve the reliability of the quality of the LCD panel.
