Mask plate outer side component and assembly, color film substrate, manufacturing method of color film substrate, and display panel

Abstract

The invention provides a mask plate outer side component. The mask plate outer side component is used for manufacturing a color film of a color film substrate; the color film substrate comprises a pixel area and a virtual area located on at least one side of the pixel area; the mask plate outer side component comprises a light-shielding layer and a nonopaque pattern formed in the light-shielding layer; the nonopaque pattern comprises a pixel nonopaque pattern and a virtual nonopaque pattern; the virtual nonopaque pattern comprises a first virtual nonopaque pattern located on at least one sideof the pixel nonopaque pattern and at least one second virtual nonopaque pattern located on the outer side of the first virtual nonopaque pattern; the second virtual nonopaque pattern comprises a plurality of virtual pattern units; the areas of the virtual pattern units are in inverse correlation with the distances between the virtual pattern units and certain sides of the corresponding first virtual nonopaque patterns. The invention further provides a mask plate assembly, the color film substrate and a manufacturing method of the color film substrate. The color film substrate has a lower filmbreaking rate.

Description

technical field [0001] The present invention relates to the field of liquid crystal display, in particular to a mask outer part, a mask assembly including the mask outer part, a color filter substrate manufactured by using the mask assembly and a manufacturing method thereof, and a mask assembly including the mask assembly. The display panel of the color filter substrate. Background technique [0002] With the development of display technology, users demand that liquid crystal display products have higher color saturation and color gamut. In order to meet customer needs, the existing technology increases the color saturation by increasing the thickness of the color filter film and matches the corresponding backlight.

Problems solved by technology

[0002] With the development of display technology, users demand that liquid crystal display products have higher color saturation and color gamut. In order to meet customer needs, the existing technology increases the color saturation by increasing the thickness of the color filter film and matches the corresponding backlight. To realize the high color gamut of the product, but the above-mentioned prior art has the following problems: such as figure 1 As shown, due to the increase in the thickness of the color filter film layer, a large step difference D1 is formed between the blue virtual pattern 101' around the color filter substrate and the substrate surface (wherein, the maximum value of D1 reaches 3.0 μm), resulting in subsequent transparent When the protective layer 102'(OC) is coated, the film breaks at the level difference

like figure 2 As shown, the light-colored stripes in area I are the location where the protective layer breaks, which seriously affects the product yield.

[0003] In order to solve the above problems, the existing technology solves the occurrence of film rupture by reducing the coating speed of the protective layer or increasing the film thickness of the protective layer. However, reducing the coating speed of the protective layer will affect the production cycle of the production line and reduce the production capacity. , increasing the thickness of the protective layer will reduce the transmittance and increase the cost
