Abstract
A pixel shift device has at least one liquid crystal structure. In the liquid crystal structure, a pair of transparent electrodes is located facing each other. A pair of alignment films is between the pair of transparent electrodes. Each of the pair of alignment films has mutually anti-parallel alignment direction. A nematic liquid crystal layer is within the pair of alignment films.
