An electrically-driven liquid crystal lens (1000), which can achieve not only a gentle parabolic lens plane when being realized via alignment of liquid crystals based on a changed electrode configuration, but also a reduced cell gap of a liquid crystal layer and a stable profile even in a large-area display device, and a stereoscopic display device using the same are disclosed. The electrically-driven liquid crystal lens includes first (100) and second (200) substrates arranged opposite each other and each defining an active region including a plurality of lens regions (L) and a pad region at the outer side of the active region (See fig 7), a plurality of first electrodes (101) formed on the first substrate to correspond to the respective lens regions and spaced apart from one another by different distances between the centers of the neighboring first electrodes in each lens region, a second electrode formed over the entire surface of the second substrate, a voltage source to apply different voltages to the plurality of first electrodes and to apply a ground voltage to the second electrode, and a liquid crystal layer filled between the first substrate and the second substrate. |
