Document Type and Number:
WIPO Patent Application WO/2019/165687
Kind Code:
A1
Abstract:
A photo-alignment material, a liquid crystal display panel and a preparation method therefor. A chemical structural formula of the photo-alignment material comprises a first group, a second group, a third group, and a fourth group which are connected in sequence, wherein the first group is a group having an alignment anchoring function; the second group is a linking group; the third group is a group with a structural formula of one or more photosensitive chalcones; and the fourth group is an alignment group having linear-chain type or branched-chain type alkyl with 3-15 carbon atoms. In this manner, the preparation process of the liquid crystal display panel can be simplified, and the quality of a product is improved.
