Abstract
A display device capable of actively controlling a viewing angle by an electrical signal, and a method for driving the same, are discussed. The display device in one embodiment includes a first substrate with a plurality of pixels, and a second substrate with convex lens, the second substrate facing the first substrate. Each of the plurality of pixels includes a main pixel and a viewing angle control pixel, and an image is displayed on both the main pixel and the viewing angle control pixel in a wide viewing angle mode. Further, an image is displayed on the main pixel, and a black is displayed on the viewing angle control pixel in a narrow viewing angle mode.
