Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] figure 1 It is a schematic cross-sectional structure diagram of a color filter substrate in the prior art. Such as figure 1 As shown, the color filter substrate 001 includes a base substrate 01 , a light-shielding layer 03 disposed on the base substrate 01 , a color-resist layer 04 , and a planarization layer 02 disposed on the side of the color-resist layer 04 away from the base substrate. Wherein, the light-shielding layer 03 can block the traces, thin-film transistors, fingerprint identification elemen...

Abstract

The invention discloses a color film substrate, a display panel and a display device. The color film substrate has a display area and a non-display area. The color film substrate comprises a substrateand a planarization layer, and a light shielding layer and a color resistance layer located between the substrate and the planarization layer, wherein the color resistance layer comprises a pluralityof display color resistance patterns and a plurality of dummy color resistance patterns; the display color resistance pattern is arranged in the display area, and the dummy color resistance pattern is arranged in the non-display area; the light shielding layer located in the display area comprises a plurality of opening structures, and the orthographic projection of the display color resistance pattern on the substrate covers the orthographic projection of the opening structure on the substrate; the light shielding layer located in the non-display area is provided with a plurality of first grooves, and the thickness of the light shielding layer at each position in the non-display area is greater than 0. The thickness of the display area and the thickness of the non-display area of the color film substrate of the embodiment of the invention can tend to be consistent, so as to improve the box thickness difference between the display area and the non-display area in the display panel, thus improving the display effect and the product yield.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a color filter substrate, a display panel, and a display device. Background technique [0002] With the development of science and technology, liquid crystal display devices are widely used in mobile terminals such as vehicle-mounted video players or tablet computers. The liquid crystal display panel realizes color display through a color filter substrate (Color Filter, CF). [0003] Wherein, the color filter substrate mainly includes a base substrate, a light shielding layer, a color resist layer and a planarization layer arranged on the base substrate. At present, it is often necessary to set a large area of ​​dummy color resistance in the peripheral area of ​​the color filter substrate. The dummy color resistance can protect the display color resistance of the display area and at the same time increase the non-display of the color filter substrate;...
