Abstract:
1. A liquid crystal lens electrically driven, comprising: first and second substrates arranged to face each other to have a plurality of first and second lens regions with pitches different from each other; a plurality of first electrodes respectively formed at the first lens regions of the first substrate in one direction; a plurality of second electrodes respectively formed at the second lens regions of the second substrate in one direction; a voltage source for generating: a liquid crystal layer filled between the first substrate and the second substrate, wherein the first voltage group comprises voltages which become higher as the first region goes from the center to the edge portion to be applied to the first electrodes, and wherein the second voltage group comprises voltages which become the higher as the second lens region goes from a peak point of a sub-region to a boundary of the sub-region to be applied to the second electrodes, such that each of a plurality of the sub-regions of the second lens region comprises the peak point.
