Abstract
A display device that can selectively display 2D and 3D images is provided. The display device includes a backlight unit, a liquid crystal device, and a light control device including two polarizing plates interposed between the backlight and the liquid crystal device each of the polarizing plates having a polarized pattern, and one of the polarizing plates being moveable. Therefore, the display device can selectively display 2D and 3D images by moving one of the polarizing plates parallel to the other polarizing plate, and a width of a light valve can be controlled by the degree of non-alignment of the polarizing plates.
