The present invention provides a pixel structure including a plurality of pixel cells arranged in a matrix. The pixel cells are defined by a plurality of scan lines and data lines that being mutually intersected. Each pixel cell includes a first discharge control switch, a second discharge control switch, a main pixel area and a sub-pixel region is disposed adjacent the latter. The main pixel area includes a main pixel electrode and a main charge control switch. The sub-pixel area includes a sub-pixel electrode and a sub-charge control switch. The main pixel electrode receives display signals by the main charge control switch. The sub-pixel electrode receives display signals by the sub-charge control switch. The scan line transmitting scan signals of its present pixel cell and the sub-pixel electrode of the above pixel cell are connected by said first discharge control switch.
