MASK FOR PHOTOALIGNING AN ALIGNEMENT LAYER, PHOTOALIGNMENT METHOD USING THE SAME, AND LIQUID CRYSTAL DISPLAY HAVING THE PHOTOALIGNED ALIGNEMENT LAYER

摘要

A wide variety of different alignment polar angles can be created in the alignment layers of a liquid crystal display with just a small number of UV exposure steps by using one or a combination of overlappable UV masks, where the one or more combinations of overlappable UV masks simultaneously define a maximal transmission region, an intermediate transmission region and a nontransmitting (blocking) region. UV rays are irradiated through masks in different irradiation directions while the mask or masks are disposed in different orientations.
