Electric field driven liquid crystal lens cell and stereoscopic image display device using the same

摘要

An electric field driven liquid crystal lens including 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.
