Display panel

Abstract

The invention provides a display panel comprising a first substrate, a second substrate and a black matrix arranged between the first substrate and the second substrate. The first substrate comprises a plurality of pixel regions in matrix distribution, each pixel region having a plurality of sub-pixel regions. The second substrate is opposite the first substrate. The black matrix comprises a plurality of row shading materials and a plurality of column shading materials. Each row shading material is arranged between two adjacent pixel regions and extends in a first direction, and the row shading materials have a first thickness. Each column shading material is arranged between two adjacent sub-pixel regions and extends in a second direction, and the column shading materials have a second thickness. The second thickness is different from the first thickness, and the first direction is different from the second direction. By adjusting the thickness, the shape and the configuration of the column shading materials of the structure of the black matrix, the pixel regions are flatter, a developing agent or residual carbon is prevented from remaining in the pixel regions in the technological process, the problems such as photoresist residues are reduced, and the penetration rate of high-resolution products is increased.

Description

technical field [0001] The invention relates to a display panel. Background technique [0002] With the popularization and maturity of the display panel technology, in recent years, the main development direction is to increase the resolution, reduce the power consumption and increase the size. One of the factors affecting the resolution is the unevenness of the surface of the color filter material, which reduces the transmittance, and this factor will become more significant as the sub-pixels become smaller (the black matrix spacing is smaller). [0003] see Figure 1A as well as Figure 1B , Figure 1A It is a partial enlarged schematic diagram of the second substrate of the display panel in the prior art. Figure 1B for Figure 1A Schematic diagram of the zoomed-in view of box A1. [0004] The display panel in the prior art at least includes a first substrate (not shown in the figure), a display medium (not shown in the figure), a second substrate S2 , a black matrix B...

AI Technical Summary

Problems solved by technology

[0007] In addition, in addition to the above-mentioned problems, the smaller and smaller sub-pixels (smaller black matrix spacing) will cause developer to easily remain between the black matrix during the process, and it is difficult to completely remove the photoresist and there will be residual carbon.

This problem will also affect the transmittance of the display panel
