ABSTRACT:
An electrically-driven liquid crystal lens, which can reduce crosstalk caused at the center of an electrode, includes first and second substrates arranged opposite each other and defined, respectively, with a plurality of lens regions corresponding to each other, first electrodes formed on the first substrate between centers of the respective neighboring left and right lens regions on the first substrate, a black matrix layer formed on the first substrate to correspond to edges of the respective lens regions, the black matrix layer having a first width, second electrodes formed on the first substrate to correspond to the edges of the respective lens regions, the second electrodes having a second width smaller than the first width, a third electrode formed throughout the second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate.
