Abstract

Disclosed herein is an adjustable viewing angle display device. The display device includes a display panel composed of a first substrate, a second substrate, a display medium layer interposed therebetween, a first electrode, a second electrode and a third electrode. Pluralities of sub-pixels are defined in the display panel. The first and second electrodes are disposed on the first substrate in the sub-pixels. The first electrode is spaced apart from the second electrode. The third electrode is disposed on the second substrate. When the display device is operated in a narrow viewing angle mode, there exists a non-zero potential difference between the second electrode and the third electrode, and when the sub-pixel is at gray level of zero, the potential difference between the first electrode and the second electrode is not zero. A driving method for driving the display device is disclosed as well.
