Abstract:
1. A method of fabricating a patterned retarder, comprising: forming a retarder material layer on a substrate by coating a retarder material; irradiating a first polarized UV ray onto the retarder material layer, the first polarized UV ray having a first polarization axis; irradiating a second polarized UV ray onto the retarder material layer, the second polarized UV ray having a second polarization axis perpendicular to the first polarization axis; and baking the retarder material layer to form first and second oriented patterns alternating with each other, each of the first and second oriented patterns having an anisotropic property, wherein the retarder material has a homopolymer type where a photo-reactive group is included in a side chain, and wherein the retarder material having the homopolymer type includes identical units, and a mesogenic property is obtained by a hydrogen bonding between the photo-reactive group of one of the identical units and the photo-reactive group of another of the identical units.
