Manufacturing method of color filter substrate, color filter substrate and display panel

Abstract

The invention relates to the field of display technology, and discloses a manufacturing method of a color filter substrate, a color filter substrate and a display panel, so as to improve the manufacturing accuracy of the color filter substrate. The manufacturing method of the color filter substrate includes: forming a pattern of an alignment mark on the base substrate, and the alignment mark includes a mark corresponding to the mark used in the production of the color photoresist and an original mark used in the corresponding production of the black matrix; according to the alignment mark, in A pattern of color photoresist is formed on the base substrate, and at the same time, a copy mark coincident with the original mark is formed on the side away from the base substrate corresponding to the original mark used when making the black matrix; The pattern of the black matrix within the area defined by the color photoresist.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a color filter substrate, a color filter substrate and a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED) display devices are thin, light, wide viewing angle, active luminescence, continuously adjustable luminous color, low cost, fast response, low energy consumption, low driving voltage, and low operating temperature. With the advantages of wide range, simple production process, high luminous efficiency and flexible display, it has been listed as a promising next-generation display technology. [0003] OLED display technology can be roughly divided into three ways to realize color display: red (R), green (G), blue (B) independent pixel light-emitting mode, color conversion light-emitting mode, and the combination of white OLED and color filter. Among them, the combination of white light OLED and color filter follows th...

Problems solved by technology

The defect of the existing technology is that after the whole layer of black matrix is ​​formed on the alignment mark, due to the high shading degree of the black matrix material, the automatic alignment equipment cannot identify the corresponding mask and substrate used for making the black matrix pattern. The mark used for the alignment, resulting in the failure of normal alignment and low production accuracy
