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 includes a base substrate 1 , a light-shielding layer 2 disposed on the base substrate 1 , a color-resist layer 3 , and a planarization layer 4 disposed on the side of the color-resist layer 3 away from the base substrate. Wherein, the light-shielding layer 2 can block the traces, thin-film transistors, fingerprint identification elements, etc. ar...

Abstract

The invention discloses a color film substrate, a display panel and a display device. The color film substrate comprises a substrate; the substrate comprises a display area and a non-display area; a shading layer and a color resistance layer are located on one side of the substrate; a planarization layer is further arranged on one side, deviating from the substrate, of the color resistance layer;the display area comprises a plurality of display color resistance units, the display color resistance units comprise a plurality of display color resistance patterns with different colors, and the display color resistance patterns comprise a first display color resistance pattern; the non-display area comprises a plurality of dummy color resistance units, each dummy color resistance unit comprises at least one dummy color resistance pattern, and each dummy color resistance pattern comprises a first dummy color resistance pattern; the colors of the first display color resistance patterns are the same as these of the first dummy color resistance patterns; the thicknesses of the first dummy color resistance patterns is smaller than these of the first display color resistance patterns in thedirection perpendicular to a plane where the substrate is located. By improving the box thickness difference between the display area and the non-display area, the phenomenon of peripheral yellowing is improved, and the yield is increased.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, 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, the peripheral area of ​​the color filter substrate often needs to be provided with a large-area dummy color resist to provide support columns, and the light shielding layer in the peripheral area of ​​the color filter substrate is fully covered. However, since the planarization lay...
