Abstract
A display device includes a display panel and a voltage generating part. The display panel includes a switching element, a main pixel section, a coupling capacitor and a sub pixel section. The main pixel section is electrically connected to the switching element. The coupling capacitor has a first end electrically connected to the switching element. The sub pixel section is electrically connected to a second end of the coupling capacitor. The voltage generating part controls data voltages corresponding to a gray-scale in a range from a low gray-scale to a high gray-scale that corresponds to a saturation voltage of the sub pixel section for displaying an image. The data voltages are applied to the display panel. Therefore, the viewing angle and the luminance are improved.
