Problems solved by technology

In the liquid crystal display disclosed in the above three patents, although the transition initiation point can be generated by the transverse electric field, however, the method of digging a hole (slit) in the pixel electrode of the liquid crystal display will sacrifice the aperture ratio and reduce the brightness of the panel and other shortcomings

Abstract

The invention relates to a pixel structure which comprises a base plate, a scanning wiring, a data wiring, a common wiring, an active element, a pixel electrode, a protective layer and a rotating state auxiliary electrode. The scanning wiring and the data wiring are crossly arranged on the base plate, and a pixel area is defined on the base plate. The common wiring is arranged on the base plate and is virtually parallel with the scanning wiring. The active element is arranged in the pixel area, and is electrically connected with the scanning wiring and the data wiring. The pixel electrode is arranged in the pixel area and is electrically connected with the active element. The protective layer is arranged between the pixel electrode and the data wiring. The rotating state auxiliary electrode is arranged around the pixel electrode, and the pixel electrode and the rotating state auxiliary electrode share the same film layer. In addition, the rotating state auxiliary electrode permeates a touching window of the protective layer to electrically connect with the common wiring.

Description

technical field [0001] The present invention relates to a pixel structure and a display panel, and in particular to a pixel structure and a liquid crystal display panel suitable for an optically compensated birefringence liquid crystal display (OCB LCD). Background technique [0002] As the demand for displays is increasing day by day, the industry is fully committed to the development of related displays. Among them, the cathode ray tube (CRT) has monopolized the display market for many years because of its excellent display quality and technological maturity. However, due to the rise of the concept of green environmental protection recently, based on the characteristics of large energy consumption and large radiation generated by cathode ray tubes, and the limited space for flattening their products, cathode ray tubes cannot meet the market demand for light, thin, short , small, beautiful and low power consumption market trends. Therefore, a thin film transistor liquid c...
