Abstract

The invention discloses a color film substrate, and belongs to the field of the liquid crystal display. The color film substrate comprises a display area and a non-display area located surrounding thedisplay area; the display area comprises a first black matrix, pixel areas limited through the first block matrix, a color resistance layer located at each pixel area, and a first planarization layercovering the color resistance layer; the color resistance layer partially covers the first black matrix; the non-display area comprises a second black shading layer in whole surface laying, a cushionlayer covering the second black shading layer and a second planarization layer covering the cushion layer; the total height of the cushion layer and the second black shading layer is equal to the height of the color resistance layer. The color film substrate for flattening the display area and the non-display area can solve the problem that the periphery display is bad under the condition of notincreasing the thickness of the display area.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate and a manufacturing method thereof. Background technique [0002] Liquid crystal display has the advantages of small size, low power consumption, and no radiation. It has developed rapidly in recent years and currently occupies a dominant position in the flat panel display market. The structure of the color filter substrate is generally as follows: figure 1 As shown, it includes a display area 1 and a non-display area 2. The display area 1 includes a first black matrix 5, a pixel area defined by the first black matrix 5, a color-resist layer 6 covering the pixel area, and a color-resist layer covering the color-resist layer. The first planarization layer 8, the non-display area 2 includes a second black light-shielding layer 9, an overlapping pixel color-resist layer 14 near the edge of the display area 1, and partially covering the second...
