example 1

[0069] Example 1: If figure 1 The manufacturing method of the display substrate shown, such as Figure 4a-Figure 4e As shown, specifically, the following steps may be included:

[0070] 1. On the base substrate 1, form a pattern including a black matrix 5, such as Figure 4a shown; specifically, the formation process of the black matrix 5 graphics is similar to the formation process of the existing black matrix, and will not be repeated here;

[0071] 2. Coating green negative photoresist material on the base substrate 1 formed with black matrix 5 patterns to form a photoresist film 6, such as Figure 4b shown;

[0072] 3. Utilize mask plate 7 to carry out exposure treatment to photoresist film 6, as Figure 4c Shown; Wherein, the complete shading area of ​​mask plate 7 corresponds to the area outside the green color filter (G) pattern to be formed, and the part light-transmitting area of ​​mask plate 7 corresponds to the green color filter (G) to be formed ) the area whe...

Abstract

The invention discloses a display base plate, a manufacturing method thereof, a display panel and a display device. The display base plate comprises a substrate base plate, a color film layer positioned on the substrate base plate, and a flat layer positioned on the color film layer. Due to the fact that the color film layer is provided with at least one spherical groove sinking to the substrate base plate, the flat layer can form a structure similar to a convex lens array; when the refractive index of the color film layer is smaller than that of the flat layer, light can be gathered when passing through an interface between the flat layer and the color film layer; when the display base plate is applied to the display panel, a viewing angle of the display panel can be reduced, so that the peep-proof function of the display panel can be achieved without a peep-proof film; moreover, the light is gathered when passing through the interface between the flat layer and the color film layer, so that the display brightness of a positive viewing angle of the display panel can also be improved, and the power consumption of the display panel can be reduced under the same display brightness.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, a display panel and a display device. Background technique [0002] With the continuous development of display technology, the anti-peeping function has gradually become a hot spot that people pay attention to. Users of the display device hope that the viewing angle of the display device is small, that is, the display information can be completely received within a limited viewing angle range, so as to prevent peeping. [0003] Currently, the display device realizes the anti-peeping function by pasting an anti-peeping film on the outside of the display device. However, the anti-peeping film has disadvantages such as high cost, needing regular cleaning and maintenance, being easily damaged, and affecting the appearance of the display device. [0004] Therefore, how to make the display device realize the anti-peeping f...
