Problems solved by technology

The problem caused by this is that a coupling electric field is easily formed between the remaining ions in the black matrix of the display substrate and the electrodes of the TFT, which makes the display afterimage worse
[0003] The existing solution is to use a high-impedance type for the black matrix of the display substrate, but this requires the development of new materials, increases the production cost of the LCD panel, and causes a decline in production capacity

Embodiment Construction

[0041] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0042] figure 1 It is a structural schematic diagram of an existing color liquid crystal display panel, such as figure 1 As shown, the existing color liquid crystal display panel includes a color filter substrate and an array substrate that are arranged oppositely. The color filter substrate includes a base substrate 2, a black matrix 3 and a color photoresist layer 4 located on the base substrate 2, and The side of the substrate 2 facing away from the array substrate is provided with a transparent conductive layer 1, and a spacer 5 is provided on the color photoresist layer 4. The array substrate includes a base substrate 7 and a thin film transistor array layer 6 on the base substrate 7. , wherein, the distance between the thin film...

Abstract

The invention provides a display substrate, a manufacturing method of the display substrate, a display panel and a display device and belongs to the technical field of display. The manufacturing method of the display substrate comprises steps as follows: providing a substrate; forming a transparent conductive layer on the substrate; forming black matrix patterns on the transparent conductive layer. By means of the technical scheme, formation of a coupling electric field is avoided on the premise that the cost of the display substrate is not increased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a manufacturing method thereof, a display panel, and a display device. Background technique [0002] The ADS (Advanced Super Dimension Switch, Advanced Super Dimension Switching Technology) type black and white display based on TFT-LCD (thin film transistor-liquid crystal display, thin film transistor liquid crystal display) technology includes an array substrate and a display substrate arranged in a box with the array substrate , Compared with the color filter substrate of the ADS color display, there are fewer color photoresist layers on the display substrate. Therefore, after forming a liquid crystal display panel, the distance between the display substrate and the TFT substrate is shortened by 2-3 μm. The problem caused by this is that a coupling electric field is easily formed between the remaining ions in the black matrix of the display sub...
