Abstract
A display substrate, a display device, and a fine metal mask provided by the present disclosure, the display substrate including a base substrate; a plurality of mutually independent first electrodes, which are located on the base substrate; a pixel definition layer, which is located on the side of a layer in which the plurality of first electrodes are located away from the base substrate; a light-emitting material layer, which is located on the side of the pixel definition layer away from the base substrate; and a support layer, which is located above the pixel definition layer and is in direct contact with the light-emitting parts.
Claims7
A display substrate, comprising:
- a base substrate;
- a plurality of mutually independent first electrodes on the base substrate;
- a pixel definition layer on a side away from the base substrate, of a layer where the plurality of first electrodes are;
- wherein the pixel definition layer comprises a plurality of pixel openings, an overlapping portion and a non-overlapping portion are provided between the pixel opening and the first electrode, the non-overlapping portion surrounds the overlapping portion, and the pixel definition layer covers the non-overlapping portion and a gap between the first electrodes;
- a light-emitting material layer on a side away from the base substrate, of the pixel definition layer;
- wherein the light-emitting material layer comprises a plurality of light-emitting parts, and the light-emitting parts extend from the pixel openings to the pixel definition layer;
- and
- a support layer on the pixel definition layer;
- wherein the support layer is in direct contact with the light-emitting parts, and an orthographic projection of the support layer on the base substrate overlaps orthographic projections of gaps among the plurality of first electrodes on the base substrate;
- wherein a lateral surface of the support layer is in contact with a lateral surface of the light-emitting part;
- a surface edge on a side away from the base substrate, of the support layer is in contact with a surface edge on a side facing the base substrate, of the light-emitting part;
- and
- a gap is provided between adjacent light-emitting parts on a surface on the side, away from the base substrate, of the support layer.
