Abstract
Disclosed are an electrically-driven liquid crystal lens which includes a light shade to be switched on/off according to whether or not voltage is applied, reducing a cell gap of a liquid crystal layer, and a stereoscopic display device using the same, the electrically-driven liquid crystal lens includes first and second substrates opposite each other and each including plural lens regions and a light shade provided at a boundary of each lens region, first electrodes formed in a given direction on the first substrate in each lens region, a second electrode formed on the second substrate and having an aperture corresponding to the light shade, first and second light shade switching electrodes formed at the light shade and extending parallel to the first electrodes, a liquid crystal layer between both the substrates, and a polarizer plate formed above the second substrate and having a first transmission axis.
