Array substrate, manufacturing method thereof and curved surface liquid crystal display panel

Abstract

The invention provides an array substrate, a manufacturing method thereof and a curved surface liquid crystal display panel. The array substrate comprises: a substrate, a metal shielding layer arranged on the substrate and comprising a plurality of metal shielding lines, an insulating layer arranged on the metal shielding layer and the exposed substrate, a data line arranged on the insulating layer, a first passivation layer arranged on the data line and the exposed substrate, a color barrier layer arranged on the first passivation layer, a second passivation layer arranged on the color barrier layer, and an ITO layer arranged on the second passivation layer and used for forming a pixel electrode, wherein the metal shielding line close to the data line directly extends to the bottom of the data line to be overlapped with the data line. The array substrate provided by the invention can eliminate light leakage gaps on both sides of the data line, and can also omit a black matrix on the direction of the data line.

Description

technical field [0001] The invention belongs to the technical field of manufacturing liquid crystal display panels, and in particular relates to an array substrate, a manufacturing method, and a curved liquid crystal display panel. Background technique [0002] Such as Figure 1a Shown is a schematic diagram of a pixel structure of an existing conventional array substrate, Figure 1b for Figure 1a A zoomed-in schematic of the local region in the middle. Figure 1b It can be seen that there is usually a distance of 2.5-3.0 um between the metal light-shielding layer SM and the data line DL. The area corresponding to this distance has no metal shading, and there is no ITO electrode to control the liquid crystal molecules, and the backlight will always transmit light after it is turned on. Therefore, generally, a black matrix BM is arranged on the side of the color filter substrate corresponding to the array substrate, and the black matrix BM is used to shield this area, such...

AI Technical Summary

Problems solved by technology

For curved liquid crystal display panels, because the bending degree of the color filter substrate and the array substrate are inconsistent, the vertical BM on the color filter substrate will deviate from the pixel display area of ​​the array substrate, causing dark lines on one side of the pixel and light leakage on the other side, so black Matrix BM design is not suitable for curved LCD panels
