摘要： A display device includes a display panel, an optical member, and a display driver. The display panel is configured to display a plurality of 2D images. The optical member is configured to refract 2D image display light displayed in a display area of the display panel into a first refraction direction or a second refraction direction to output 3D stereoscopic image display light. The display driver is configured to control a refraction direction of the 3D stereoscopic image display light by dividing a 3D stereoscopic image display period of at least one frame into first and second time-division frames and supplying driving voltages to the optical member in each of the first and second time-division frames.
