Abstract
A liquid crystal (LC) pixel, a method for providing an output thereof and a liquid crystal display device are provided. The LC pixel includes: a first electrode (5) having comb-like structures; an alignment layer (6) adjacent to the first electrode (5), wherein the alignment layer (6) is patterned with local areas that are different from the remaining area of the alignment layer (6) and wherein the local areas are configured to produce local defects in initial orientation in an LC layer (1) upon application of a control voltage; and the LC layer (1), configured to asymmetrically diffract light passing through the LC layer (1) based on configuration of the comb-like structures and the alignment layer (6).
