Claim:
1. An optical modulation device comprising: a first plate including a first substrate, a lower plate electrode, a first electrode layer, which includes a first electrode array including a plurality of first electrodes, and a first aligner, wherein the lower plate electrode is formed on the first substrate, and the first electrode layer and the first aligner are formed on the lower plate electrode; a second plate facing the first plate, the second plate includes an upper plate electrode and a second aligner; and a liquid crystal layer disposed between the first plate and the second plate, the liquid crystal layer including a plurality of liquid crystal molecules, wherein an alignment direction of the first aligner and an alignment direction of the second aligner are substantially parallel with each other, wherein the optical modulation device further comprises: a first zone, wherein voltages applied to a first plurality of first electrodes in the first zone increase or decrease in a first direction in which the plurality of first electrodes is arranged in the first zone.
