Abstract
A display device able to provide uniform display brightness comprises a first substrate and spaced common electrodes which on the first substrate. The common electrodes are used for display and include at least one first sub-electrode and a plurality of second sub-electrodes, an area of each first sub-electrode being smaller than an area of any one of the second sub-electrodes. When the device is in display, a first common electrode voltage is applied to the first sub-electrodes, and a second common electrode voltage is applied to the second sub-electrode, the voltage value of each being different.
