Embodiment 1

[0031] This embodiment provides a color filter substrate, which includes a display area for display, a glue area surrounding the display area, a transition area between the display area and the glue area, and a color filter is arranged in the display area and the transition area. a light film and a black matrix, the black matrix in the display area has an opening corresponding to the light-transmitting area of ​​the sub-pixel, the black matrix covers the glue-coated area, and

[0032] The distribution density of the color filter films in the transition area is smaller than the distribution density of the color filter films in the display area.

[0033] In the color filter substrate of this embodiment, the distribution density of the color filter film in the transition area is lower than that of the color filter film in the display area, so that the distribution density of the film layers (black matrix and color filter film) in the two areas is lower than that of the color filte...

Embodiment 2

[0035] Such as Figure 3 to Figure 7 As shown, this embodiment provides a color filter substrate 1, the color filter substrate 1 is used to form a display panel with a box-matching substrate (such as an array substrate 2), and filters the light emitted by the display panel, thereby realizing Display in color.

[0036] Specifically, the color filter substrate 1 includes a display area 91 , a glue area 93 , and a transition area 92 . Wherein, the display area 91 is used for displaying; and the glue-coating area 93 surrounds the display area 91 and is used for coating the frame sealant 3 when the display panel is formed on the box; in order to prevent the frame sealant 3 from entering the display area 91, the A transition area 92 is also provided between the display area 91 and the glue area 93 .

[0037] Wherein, both the display area 91 and the transition area 92 are provided with a color filter film 11 and a black matrix 12 for blocking light.

[0038] In the display area 9...

Abstract

The invention provides a color film substrate, a preparation method thereof and a display panel, and belongs to the technical field of color film substrates. The color film substrate, the preparation method thereof and the display panel can solve the problem that an existing color film substrate can cause light leakage at the edge of a display panel. The color film substrate comprises a display area for displaying, a gluing area surrounding the display area and a transition area between the display area and the gluing area, the display area and the transition area are each provided with a color filter coating and a black matrix, the black matrix in the display area is provided with an opening corresponding to a sub-pixel light transmitting area, the black matrixes cover the transition area, and the distribution density of the color filter coating in the transition area is smaller than that of the color filter coating in the display area.

Description

technical field [0001] The invention belongs to the technical field of color filter substrates, and in particular relates to a color filter substrate, a preparation method thereof, and a display panel. Background technique [0002] Such as figure 1 , figure 2 As shown, the color filter substrate 1 of a liquid crystal display device or the like includes a display area 91 for display and a glue-coated area 93 surrounding the display area 91. The glue-coated area 93 is used for coating the sealant 3. In order to prevent the sealant 3 from Entering the display area 91, a transition area 92 is provided between the glue application area 93 and the display area 91. Wherein, the display area 91 is provided with a black matrix 12, and the black matrix 12 is opened at the light-transmitting area corresponding to each sub-pixel; there is also a color filter film 11 covering the light-transmitting area of ​​each sub-pixel in the display area 91, because the same column of sub-pixels ...
