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

Abstract

The invention discloses a color film substrate, a manufacturing method of the color film substrate and a display panel, the color film substrate is provided with a display area and a non-display areasurrounding the display area, and the non-display area is defined to comprise a first non-display area right opposite to a double-layer metal wiring area of an array substrate and a second non-displayarea right opposite to a single-layer metal wiring area of the array substrate. The color film substrate further comprises a substrate base plate; a black matrix layer which is arranged on one surface of the substrate base plate, wherein a first protruding part is formed on the surface, deviating from the substrate base plate, of the black matrix layer located in the second non-display area; anda conducting layer which is arranged on one side, deviating from the substrate, of the black matrix layer, and is jacked by the first protruding part to form a second protruding part. According to thetechnical scheme, when the particle size of a gap supporting ball is calculated according to the longitudinal sections of the first non-display area and the second non-display area, the particle sizeof the gap supporting ball is uniform, and then it is guaranteed that the box thickness of the display panel is uniform.

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, coating of frame sealant, coating of gold balls, vacuum assembly into cells, cutting, etc. The coating of the s...

Problems solved by technology

The selection of the space ball is a fixed particle size. When calculating the space ball particle size on the vertical plane where the non-display A area (the first non-display area, double-layer metal line area) is located, for the non-display B area (the second non-display area) display area, single-layer metal wire area), the space ball particle size is relatively small; when the space ball particle size is calculated on the vertical plane where the non-display B area is located, for the non-display A area, the space ball particle size is relatively small Large, it is easy to cause uneven thickness of the box around the display panel
