Abstract
A display substrate and a forming method thereof, a display panel and a display device are provided. The display substrate includes: a base substrate, a display functional layer on the base substrate, and an optical structure arranged at a side of the base substrate. The optical structure is used to control an emergent angle of light from the display functional layer to be within a predetermined angle range.

A display substrate, comprising:
- a base substrate;
- a display functional layer on the base substrate;
- and
- an optical structure at a side of the base substrate, wherein the optical structure is configured to control an emergent angle of light from the display functional layer to be within a predetermined angle range;
- wherein the optical structure comprises a plurality of light-shielding patterns spaced from each other and an extending direction of each light-shielding pattern is perpendicular to a first plane, wherein the first plane is parallel to the base substrate.
