Abstract
The display substrate includes: a substrate, a plurality of pixel units at a side of the substrate, a color filter layer at a light emergent side of the pixel units, a light processing structure, and a cover plate at a side of the color filter layer facing away from the substrate. Each of the pixel units includes a plurality of sub-pixel units. The color filter layer includes a plurality of color filter units arranged in one-to-one correspondence to the sub-pixel units. The color filter units are closely arranged. An orthographic projection of the light processing structure on the substrate covers a junction of the color filter units of different colors. The light processing structure is configured to prevent light rays emitted from the sub-pixel units and having an angle greater than a critical angle of total reflection of the cover plate from being emitted from the cover plate.
