Abstract
A vertical alignment liquid crystal display device (VA-LCD) includes a display panel. The display panel includes a plurality of pixels. Each pixel unit includes a first thin film transistor (TFT), a second TFT, and a liquid crystal capacitor having a pixel electrode and a common electrode. The common electrode is applied with a common voltage, a first gray voltage is applied to the pixel electrode through a first TFT, and a second gray voltage is applied to the pixel electrode through a second TFT different from the first gray voltage, such that liquid crystal capacitor maintains two different gray voltages in a display frame time of the VA-LCD.
