Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0039] An embodiment of the present invention provides a display substrate 30, such as figure 2 As shown, the display substrate 30 is also provided with: a groove 31 corresponding to the spacer for nesting the spacer, the groove 31 is formed by photoresist, and the bottom surface of the groove 31 is higher than the pixel area on the display substrate the height of.

[0040] This embodiment provides a display substrate 30, on which a groove 31 corresponding to a spacer is provided, and the spacer is generally provided on another substrate that is in a box with the display substrate 30, or the spacer can also be independent of the substrate set up. After the box is ...

Abstract

The invention discloses a display substrate, a preparation method thereof, and a display device, relates to the field of display, and solves the problem that the existing spacer can slide out of a groove easily so as to cause bad display without an additional work procedure. The provided display substrate is further provided with a groove corresponding to a spacer and used for embedding the spacer, wherein the groove is formed by photoresist, and the bottom of the groove is higher than a pixel area on the display substrate.

Description

technical field [0001] The invention relates to the display field, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Due to the advantages of zero radiation, low power consumption, small heat dissipation, small size, accurate image restoration, and sharp character display, liquid crystal displays have widely replaced traditional CRT display devices. [0003] A liquid crystal display mainly includes a color filter substrate, an array substrate, and a liquid crystal sandwiched between the two. In order to maintain the thickness of the cell between the color filter substrate and the array substrate in the liquid crystal display, a spacer is usually required. Such as figure 1 As shown, the liquid crystal display is provided with columnar main spacers 4 and sub-spacers 5 on the color filter substrate 20, and first grooves 14 and 14 corresponding to the above-mentioned main and sub-spacers are formed on the arr...
