Abstract:
1. An electrically-driven liquid crystal lens comprising: first and second substrates arranged opposite each other and each including a plurality of lens regions; a plurality of first electrodes formed on the first substrate to correspond to the respective lens regions while being spaced apart from one another, to which voltages gradually increasing from the center to the edge of each lens region are applied; a second electrode formed over the entire surface of the second substrate; a first alignment film formed over the entire surface of the first substrate including the first electrodes and having an alignment direction parallel to or perpendicular to a longitudinal direction of the first electrodes; a second alignment film formed on the second electrode and having an anti-parallel alignment direction relative to the first alignment film; and a liquid crystal layer filled between the first substrate and the second substrate.
