Abstract: A pixel structure of a display is disclosed, and includes: a first pixel region and a second pixel region adjacent to the first pixel region. The first pixel region has a first direct-current (DC) residual electric field, the second pixel region has a second DC residual electric field, and a direction of the first DC residual electric field and a direction of the second DC residual electric field are opposite to each other. An alternating electrode structure design is adopted to reduce or eliminate residual ions accumulated between the insulating layer and the electrodes, thereby reducing or eliminating an image-sticking phenomenon.
