摘要： A display panel, including a light-emitting base plate including light-emitting devices arranged in an array; first light-extracting layers, located on light-outlet sides of at least a part of the light-emitting devices, each including prisms extending along a first direction and arranged along a second direction; and second light-extracting layers, located on the light-outlet sides of the light-emitting devices, and on a side of the first light-extracting layers away from the light-emitting base plate, each including convex lenses arranged in an array, wherein an orthographic projection of the first light-extracting layer on the light-emitting base plate is within an orthographic projection of the second light-extracting layer on the light-emitting base plate, a maximum size of the prism along the second direction is less than or equal to a maximum size of the convex lens along the second direction, and the first direction intersects the second direction.

摘要： A display substrate includes a first base substrate; a reflective layer on the first base substrate; a color conversion layer on a side of the reflective layer away from the first base substrate; and a plurality of light sources in an inter-subpixel region and a color filter comprising a plurality of color filter blocks at least partially in a plurality of subpixel regions, respectively, on a side of the color conversion layer away from the reflective layer. One or more light sources of the plurality of light sources are in a first gap between two adjacent color filter blocks of the plurality of color filter blocks. An orthographic projection of the plurality of light sources and an orthographic projection of the color conversion layer on a plane perpendicular to a surface of the first base substrate and intersecting the plurality of light sources and the color conversion layer are non-overlapping.
