Pixel structure of in-plane switching LCD panel and manufacturing method thereof

Abstract

The invention discloses a pixel structure of plane direction conversion liquid crystal panel, which comprises the following parts: film transistor, dielectric layer, multiple driving electrodes and multiple sharing electrodes, wherein the film transistor is set on the base plate, which is connected to the scanning line and data line; the driving electrode and sharing electrode are inserted in the dielectric layer with mutual interpenetration allocation; the driving electrode connects the film transistor; the pixel structure can improve the imperfect direction-mating condition of two electrode sides, which reduces the needed photomask quantity in the manufacturing craft.

Description

technical field [0001] The present invention relates to a pixel structure and a manufacturing method thereof, and in particular to a pixel structure of a plane direction switching liquid crystal display panel and a manufacturing method thereof. Background technique [0002] With the high development of multimedia technology, most of the transmission of image information has now been converted from analog to digital transmission, and in order to match the modern life style, the volume of video or image devices is also becoming thinner and thinner. Although the traditional cathode ray tube (Cathode Ray Tube, CRT) display has the advantages of excellent display quality and low cost, due to the structure of its internal electron gun, the display cannot meet the requirements of thinning, light weight and low power consumption, and There are also problems such as radiation damage to the eyes when the user watches. Therefore, with the maturity of optoelectronic technology and semi...

In this way, during the alignment process, due to the included angle θ between the alignment direction D of the alignment film 150 and the extension direction of the electrodes 130 and 140, poor liquid crystal alignment may occur in the regions 144 on both sides of the electrodes, resulting in liquid crystal molecules Can't rotate properly, thus reducing the display quality of the LCD monitor

In addition, the known manufacturing process of the pixel structure of the plane orientation switching liquid crystal display panel usually requires five photomask manufacturing processes, and when defining the source / drain, part of the channel layer may also be etched, so not only the manufacturing process time Longer, and the pass rate of its manufacturing process can not be effectively improved
