Problems solved by technology

[0004] Currently, the driving electrodes in the pixel structure of the In-Plane Switching (IPS) LCD panel are limited by the arrangement of the driving electrodes and the manufacturing process tolerance. The edges of the driving electrodes are aligned with the edges of the black matrix, so that the existing pixels The opening and the light transmittance are not high

Abstract

The invention relates to a display panel. The display panel comprises a first substrate and a second substrate which are relative to each other, and a liquid crystal layer which is arranged on the middle of the first substrate and the second substrate. The display panel also consists of a plurality of pixel structures and a black matrix. The pixel structures, which are arranged on a first surface of the first substrate, include a first driving electrode which consists of a first junction, a plurality of first branch electrodes, and a plurality of first end electrodes. For each of the first branch electrodes, its electrical property of a first end is connected with the first junction, while the electrical property of a second end is connected with the first end electrode. The first end and the second end are relative to each other. The black matrix is positioned on a second surface of the second substrate. The second surface is relative to the first surface. The black matrix, in the thickness direction of the first substrate, is provided with vertical projection on the first surface. There are some overlaps between the fist junction and the vertical projection. The display panel disclosed by the invention is provided with high ray transmittance.

Description

technical field [0001] The invention belongs to the field of display technology, and relates to a liquid crystal display panel driven by a horizontal electric field. Background technique [0002] At present, the market is oriented toward high contrast ratio, no gray scale inversion, high brightness, and high color saturation for TFT liquid crystal display panels. , rapid response (response) and wide viewing angle (viewing angle) and other directions. Currently common wide viewing angle technologies include twisted nematic liquid crystal (TN) plus wide viewing film (wide viewing film), in-plane switching (In-Plane Switching, IPS) liquid crystal display panel, fringe field switching (Fringe Field Switching) , FFS) liquid crystal display panel and multi-domain vertical alignment (Multi-domain Vertical Alignment, MVA) liquid crystal display panel. [0003] In-Plane Switching (IPS) liquid crystal display panels generate a plane electric field between the electrodes of the pixel...
