Abstract
A display device with low power consumption and high display quality is provided. The display device includes first and second electrodes. One pixel includes a region in which the distance between the first electrode and the second electrode is constant and a region in which the distance varies; this structure allows the switching operation of liquid crystal to start in a predetermined region, thereby improving the stability of the operation of the liquid crystal. A pixel region is divided into two regions in which the liquid crystals are aligned in the two respective directions when switching is performed, whereby viewing angle characteristics are improved. Furthermore, the supply of a potential to a third electrode suppresses alignment disorder of the liquid crystal and improves the display quality.
