Problems solved by technology
[0006] The purpose of the present invention is to overcome the problem of the overlapping of the color layer and the light-shielding layer at the corresponding opening in the prior art, and to provide a color filter substrate, which can eliminate the angular difference. Step difference, which greatly reduces the unexpected refraction of light after passing through the color filter substrate

Embodiment Construction
[0035] In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left, right" usually refer to the orientations shown in the drawings and the orientations in practical applications, "inner, lower, left, right" The inside and outside of the contour of the "outside" part.
[0036] The invention provides a color filter substrate, such as figure 2 As shown in , the color filter substrate 2 includes a substrate 20 , a black matrix 22 , a first transparent layer 24 and a color filter layer 28 . Wherein, the substrate 20 has a first sub-pixel area, a second sub-pixel area and a third sub-pixel area; the black matrix 22 is located on the substrate 20, combined with figure 2 and Figure 3aAs shown in , the black matrix 22 includes a first opening 23a, a second opening 23b and a third opening 23c respectively corresponding to the first sub-pixel area, the second sub-pixel area and the third sub-pixel area , it can be understood ...

The invention relates to the field of display and discloses a color film substrate, a preparation method of the color film substrate and a display panel. The color film substrate comprises a substrate(20), black matrixes (22), first transparent layers (24) as well as first colored subpixel layers (28a), second colored subpixel layers (28b) and third colored subpixel layers (28c), wherein the substrate (20) is provided with first subpixel areas, second subpixel areas and third subpixel areas; the black matrixes (22) are located on the substrate and have first openings (23a), second openings (23b) and third openings (23c) which correspond to the first subpixel areas, the second subpixel areas and the third subpixel areas respectively; the first openings, the second openings and the third openings are filled with the first transparent layers (24); the first colored subpixel layers (28a), the second colored subpixel layers (28b) and the third colored subpixel layers (28c) are located above the first transparent layers and correspond to the first openings, the second openings and the third openings respectively. The color film substrate can eliminate angular segment gaps and the phenomenon of unexpected refraction produced when light passes the color film substrate is reduced.
Description
technical field [0001] The present invention relates to the display field, in particular to a color filter substrate, a method for preparing the color filter substrate, and a display panel. Background technique [0002] Color filter (Color filter) is a key component of liquid crystal flat panel display colorization. A color filter is an optical filter that expresses color. It can precisely select the small range of light waves to be passed, while reflecting off other undesired wave bands. CF is a key component of LCD colorization. LCD is a non-active light-emitting component, and its color display must provide a light source through the internal backlight module (transmissive LCD) or external ambient incident light (reflective or semi-transmissive LCD), and then cooperate with the driver IC (Drive IC) and liquid crystal (Liquid Crystal) control to form a grayscale display (Gray Scale), and then through the red (R), green (G), blue (B) color layers of the color filter to pr...
