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.
