Abstract

The embodiment of the invention provides a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises an array substrate which comprises a display area and a non-display area; a color film substrate, a common electrode being arranged on the color film substrate, and the common electrode being opposite to the display area and the non-display area; aliquid crystal molecular layer, arranged between the array substrate and the color film substrate; and a voltage alignment circuit, electrically connected with the display area and the non-display area respectively, and used for applying alignment voltage to the display area and the non-display area, so that an alignment electric field between the non-display area and the common electrode is stronger than that between the display area and the common electrode. According to the liquid crystal display panel and the liquid crystal display device, a large alignment electric field is provided in the non-display area, so that the pretilt angle of liquid crystal molecules in the non-display area is large, liquid crystal in the display area can be pushed to rapidly topple over in the display process, and then the response speed is increased.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular, to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Patterned vertical alignment technology (PVA, patterned vertical alignment) is currently the mainstream technology for vertical alignment (VA, vertical alignment) thin film transistor liquid crystal display (TFT-LCD) to achieve wide viewing angle. This technology uses a patterned transparent ITO pixel electrode. By applying a voltage, the liquid crystal molecules are divided into multiple domains by the tilting orientation under the action of an electric field. In order to reduce the response time, PVA-type TFT-LCD needs to be aligned in advance, that is, to apply a voltage between the pixel electrode and the common electrode, and to irradiate with ultraviolet light to solidify the liquid crystal alignment and generate a pre-tilt angle. The larger the appli...
