Abstract
The invention provides a vertical alignment liquid crystal panel, which includes a first glass substrate, a second glass substrate, and a liquid crystal layer that includes negative liquid crystal containing liquid crystal molecules having a pre-tilt angle of 0°-7°, chiral agent, and a photo- or heat-polymerizable polymer. The first glass substrate includes a liquid crystal panel driving circuit, which includes a gate driver, a source driver, a plurality of gate lines, and a plurality of data lines. The gate lines and the data lines define a plurality of pixel units, each of which includes a thin-film transistor, a common electrode, and a pixel electrode. The source driver applies a driving voltage of 0-6V via the thin-film transistor to the pixel electrode. The present invention improves elastic energy between the liquid crystal molecules and thus avoids image sticking caused by long term displaying of the same image at the same location.
