Abstract:
1. A stereoscopic display device comprising: a display panel to emit a 2-dimensional (2D) image signal; and an electric field driven liquid crystal lens that converts the 2D image signal into a 3-dimensional (3D) image signal, the electric field driven liquid crystal lens comprising: a first substrate and a second substrate arranged opposite each other; a first plurality of split electrodes formed on the first substrate, each of the first plurality of split electrodes corresponding to one of a plurality of lens regions; a second plurality of split electrodes formed on the first plurality of split electrodes, each of the second plurality of split electrodes corresponding to one of the plurality of lens regions; a second electrode formed over an entire first surface of the second substrate; a first alignment film formed over an entire surface of the first substrate including the first and second plurality of split electrodes, the first alignment film having a first rubbing direction; a liquid crystal layer disposed between the first substrate and the second substrate; and a polarizer plate formed on a second surface of the second substrate, the polarizer plate having a transmission axis that is in a range of ±10 degrees from the first rubbing direction.
