Abstract: A display substrate and a manufacturing method therefor, and a display device. The display substrate comprises a display structure layer (100), a packaging structure layer (200) provided on the display structure layer (100), and a color film structure layer (300) provided on the side of the packaging structure layer (200) farthest from the display structure layer, wherein the packaging structure layer (200) at least comprises a light extraction structure (43) used for improving the light emitting efficiency.

Abstract: A display panel includes: a light-emitting baseplate including a plurality of light-emitting components arranged in array; a first light extraction layer located at a light-emitting side of the light-emitting baseplate and including a plurality of first light extraction patterns, orthographic projections of the plurality of first light extraction patterns on the light-emitting baseplate covering at least part area of the light-emitting components; a color filter layer including a plurality of filter patterns, orthographic projections of the plurality of filter patterns on the light-emitting baseplate covering orthographic projections of the plurality of light-emitting components on the light-emitting baseplate; and a second light extraction layer including a plurality of second light extraction patterns, orthographic projections of the second light extraction patterns on the light-emitting baseplate being within the orthographic projections of the plurality of filter patterns on the light-emitting baseplate.

Abstract: A display substrate and a display device are provided, the display substrate includes a driving circuit substrate, a plurality of first electrodes and a pixel definition layer, and the driving circuit substrate includes a plurality of pixel driving circuits and a protective insulating layer. The plurality of first electrodes are respectively electrically connected to the output terminals of the plurality of pixel driving circuits through the plurality of first vias in the protective insulating layer, and each first electrode includes a first sub-electrode layer, a second sub-electrode layer and a transition layer. The first sub-electrode layer is electrically connected to the second sub-electrode layer through the first opening in the transition layer. An orthographic projection of a first opening of at least one first electrode on the driving circuit substrate is located inside an orthographic projection of the pixel definition layer on the driving circuit substrate.
