Abstract: Disclosed herein is a display device with an adjustable viewing angle. The display device at least includes a first sub-pixel and a second sub-pixel adjacent to the first sub-pixel. When the display device is operated in a wide viewing angle mode, the first and second sub-pixels each have an on-axis brightness at a predetermined gray level. When the display device is operated in a narrow viewing angle mode, the first and second sub-pixels respectively have a on-axis brightness at a first gray level and a second on-axis brightness at a second gray level. The on-axis brightness at the first gray level is substantially less than the on-axis brightness at the predetermined gray level of the first sub-pixel.
