ABSTRACT:
A liquid crystal device comprises: a) a liquid crystal cell including a plurality of pixels aligned on a plurality of lines and rows, each of the pixels composed of a pair of electrodes and liquid crystals provided between the pair of electrodes; and b) an optical unit including high-refractive portions positioned corresponding to the pixels, and low-refractive portions positioned next to the high-refractive portions on a plane, the high-refractive portions and low-refractive portions having the refractive indexes the ratio between which satisfies the condition for total reflection of incident light.
