Color filter substrate, manufacturing method of color filter substrate, and display panel

Abstract

The invention discloses a color filter substrate, a manufacturing method of the color filter substrate, and a display panel. The color filter substrate has a display area and a non-display area surrounding the display area, and the non-display area is defined to include the first double-layer metal wiring area facing the array substrate. A non-display area, and a second non-display area facing the single-layer metal wiring area of ​​the array substrate, the color filter substrate also includes: a base substrate; a black matrix layer, the black matrix layer is arranged on a surface of the base substrate; a lifting layer, The lifting layer is arranged on the surface of the black matrix layer away from the base substrate, and is located in the second non-display area; and the conductive layer is arranged on the side of the black matrix layer away from the base substrate, and is formed by lifting up the two lifting layers Raised part. The technical solution of the present invention aims to make the particle size of the gap support balls uniform when calculating the particle size of the gap support balls based on the longitudinal sections of the first non-display area and the second non-display area, thereby ensuring uniform cell thickness of the display panel.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a color filter substrate, a manufacturing method of the color filter substrate, and a display panel. Background technique [0002] A liquid crystal display panel (Liquid Crystal Display, LCD) is widely used due to many advantages such as a thin body, power saving, and no radiation. The TFT-LCD manufacturing process includes array manufacturing engineering, color film manufacturing engineering and liquid crystal cell manufacturing engineering. Among them, the liquid crystal cell manufacturing engineering is transferred to the liquid crystal cell engineering after the array and color film manufacturing processes are completed. The main processes of liquid crystal cell manufacturing include coating of liquid crystal alignment layer, liquid crystal dripping, frame glue coating, gold ball coating, vacuum assembly into cells, cutting, etc. The coating of the frame glue ...

AI Technical Summary

Problems solved by technology

The selection of the space ball is a fixed particle size. When the space ball particle size is calculated on the vertical plane where the non-display A area (double-layer metal line area) is located, for the non-display B area (single-layer metal line area), The particle size of the space ball is relatively small; when the particle size of the space ball is calculated on the vertical surface where the non-display area B is located, the particle size of the space ball is relatively large for the non-display area A, which will easily lead to uneven thickness of the box around the display panel
