Problems solved by technology

[0005] Although the IPS liquid crystal display panel has the advantage of a wide viewing angle, due to the design of the transverse electric field, the electric field generated between the pixel electrode 13 and the common electrode 14 is not enough to drive the liquid crystal molecules above the pixel electrode 13 and the common electrode 14 to rotate. reduce its penetration

Abstract

The invention relates to a liquid crystal display panel. The liquid crystal display panel comprises a first substrate, a second substrate arranged in the opposite direction of the first substrate and a liquid crystal layer arranged between the first substrate and the second substrate. The first substrate comprises a pixel electrode and a first common electrode. The pixel electrode comprises a plurality of first node protrudent parts; and the first common electrode comprises a plurality of second node protrudent parts in alternate arrangement with the first node protrudent parts. The second substrate comprises a second common electrode corresponding to the first common electrode. The second common electrode comprises a plurality of third node protrudent parts corresponding to the plurality of the second node protrudent parts. The liquid crystal display panel can increase the light transmission and reduce critical voltage, thereby remarkably promoting the display property of the panel.

Description

technical field [0001] The invention relates to a display device, in particular to a liquid crystal display panel. Background technique [0002] Due to the advantages of thinness, light weight, low power consumption and low radiation, liquid crystal displays have been widely used in electronic products with growth potential such as monitors, notebook computers, digital cameras and projectors. [0003] In the traditional STN liquid crystal display panel, the pixel electrodes are located on the lower substrate, and the common electrode is located on the inner surface of the upper substrate, so the angle to drive the liquid crystal to rotate is mainly vertical, and has the disadvantage of narrow viewing angle, which is not conducive to large Application of Dimensional Panels. [0004] In recent years, In-Plane Switching (IPS) liquid crystal display panels with wide viewing angle characteristics have been introduced. refer to figure 1 The IPS liquid crystal display panel 10 i...
