Array substrate, liquid crystal display panel and display device

Abstract

The invention discloses an array substrate, a liquid crystal display panel and a display device. Due to the fact that a strip-shaped, transparent and conductive shielding electrode is arranged above a grid line, the outer profile of the projection, on a substrate, of the shielding electrode surrounds the projection, on the substrate, of the grid line, and the shielding electrode, pixel electrodes and the grid line are insulating to one another, so that the shielding electrode can shield an electric field above the grid line, even if the liquid crystal display panel formed by the array substrate generates displacement due to external force, deviation of liquid crystal is not affected, and the function of preventing light leakage can be achieved; besides, due to the fact that the shielding electrode can play the light leakage prevention role, in the liquid crystal display panel formed by the array substrate, a black matrix above the grid line can be omitted, and thus the aperture opening ratio and transmittance of the display panel are increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a liquid crystal display panel and a display device. Background technique [0002] Liquid crystal displays have developed rapidly and have become mainstream flat panel displays. Since its appearance, liquid crystal displays have developed twisted nematic (TN) type, advanced ultra-dimensional field switch (Advanced DimensionSwitch, ADS) type, high aperture ratio and advanced ultra-dimensional field switch (High-Advanced DimensionSwitch, HADS) type and planar In-Plane Switch (In-PlaneSwitch, IPS) type and other types have different driving modes and display effects, and each has its own strengths. Among them, the ADS type and HADS type liquid crystal displays have shown excellent display capabilities and effects due to their unique structural characteristics and driving principles. [0003] The main difference between the ADS type and the HADS type liquid cry...

AI Technical Summary

Problems solved by technology

However, the above-mentioned ADS type liquid crystal display has some disadvantages, for example, squeezing the display panel vigorously will cause displacement of the upper substrate, and if the black matrix 11 above the gate line 21 is narrow, light leakage will easily occur

Therefore, in order to prevent light leakage, it is generally necessary to make the width of the black matrix 11 wider, but this will reduce the aperture ratio and transmittance.
