Abstract:
1. A vertical alignment liquid crystal display (VA-LCD) device, comprising: a display panel comprising a plurality of pixels, a plurality of data lines, and a plurality of scan lines intersecting the plurality of data lines, the plurality of scan lines and the plurality of data lines defining the plurality of pixels, a first pixel of the plurality of pixels comprising a first thin film transistor (TFT), a second TFT, a liquid crystal capacitor, a pixel electrode, and a common electrode, the first TFT and the second TFT being directly connected to the same liquid crystal capacitor, wherein in the first pixel, the common electrode is electrically connected to a source of the second TFT, a drain of the second TFT is electrically connected to the pixel electrode directly, a source of the first TFT is electrically connected to the first data line, a drain of the first TFT is electrically connected to the pixel electrode directly, and a switch-on resistance of the second TFT is greater than that of the first TFT, and an absolute value of a second gray voltage is lower than that of a first gray voltage, wherein in a display frame time of the VA-LCD, the common electrode is applied with a common voltage, and the first pixel maintains the first gray voltage and the second gray voltage, the first gray voltage being different from the second gray voltage, and wherein a plurality of grooves are formed in the pixel electrode and the liquid crystal molecules are aligned to different orientations.
