Abstract
An electrically-driven liquid crystal lens, and a stereoscopic display device using the same, including first and second substrates arranged opposite each other and including an active region having a plurality of lens regions and a pad region defined at an outer rim of the active region, a plurality of first electrodes formed on the first substrate to correspond to the respective lens regions and spaced apart from one another, a second electrode formed on the entire surface of the second substrate, a voltage source to apply different voltages to the plurality of first electrodes, respectively, and to apply a ground voltage to the second electrode, and a liquid crystal layer interposed between the first substrate and the second substrate.
