Patent ID: 8305550

Claim:
An electrically-driven liquid crystal lens comprising: first and second substrates arranged opposite each other and including an active region having a plurality of lens regions and a non-display region at an outer rim of the active region, wherein the non-display region has a seal pattern to enclose the active region between the first and second substrates, and a pad region at both sides of the first substrate; a plurality of first electrodes formed on the first substrate to correspond to each lens region of the plurality of lens regions and spaced apart from one another, wherein the plurality of first electrodes take the form of bars extending along a crosswire direction of the first substrate, and the plurality of first electrodes have a same width; a second electrode formed on an entire surface of the second substrate; a voltage source configured to apply gradually decreasing voltages to the plurality of first electrodes from both edges to a center of each lens region, respectively, and to apply a ground voltage to the second electrode, wherein the gradually decreasing voltages applied to the plurality of first electrodes are greater than the ground voltage; and a liquid crystal layer interposed between the first substrate and the second substrate.
