Substrate and liquid crystal display panel

Abstract

The invention provides a substrate. The substrate comprises a substrate body, a shading metal layer, a signal line layer and a pixel electrode layer. The shading metal layer is located on the substrate and is patterned to form a shielding electrode; the signal line layer is patterned to form a data line; the pixel electrode layer is patterned to form a pixel electrode; and the orthographic projection of the data line on the substrate and the orthographic projection of the shielding electrode on the substrate have an overlapping area. According to the invention, the overlapping area of the shielding electrode and the data line is increased; therefore, the shielding electrode shields the electric field of the data line more, the electric field intensity between the data line and the pixel electrode is reduced, the degree and width of light leakage are both reduced, namely, the width of the light leakage are shielded by a black matrix is reduced, the overlapping area between the black matrix and the pixel electrode is reduced, the aperture ratio f the display panel is improved, the penetration rate of the display panel is increased, and the power consumption of the display panel is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a substrate and a liquid crystal display panel. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is widely used in mobile phones, tablet computers, TVs and other products. Generally speaking, a liquid crystal display panel is a liquid crystal layer sandwiched between two parallel upper and lower substrates. between them, and apply a voltage to the electrodes of the upper and lower substrates to generate an electric field between the two substrates to control the tilting direction of the liquid crystal molecules in the liquid crystal layer, thereby displaying different pictures. With the increasing acceptance of liquid crystal display devices in the market With the increase, consumers have higher and higher requirements on the quality of liquid crystal display devices, such as viewing angle, contrast ratio, picture response rate, power consumpti...
