Abstract: A display substrate is provided. The display substrate includes a plurality of functional material layers extending at least partially across multiple subpixels. The plurality of functional material layers include a first portion in an inter-subpixel region, and a second portion in subpixel regions. The first portion includes a doped impurity. The first portion and the second portion include at least one functional material in common. A weight percentage of the doped impurity in the first portion is higher than a weight percentage of the doped impurity in the second portion. The first portion spaces apart adjacent subpixels. The second portion includes a light emitting layer of a respective subpixel.

Abstract: A light-emitting substrate includes a transparent substrate; a first metal light-shielding layer, a wiring layer and light-emitting devices. The first metal light-shielding layer is disposed on the transparent substrate. The wiring layer is disposed on a side of the first metal light-shielding layer away from the transparent substrate, and the wiring layer includes circuit traces and pads. Orthographic projections of the circuit traces and the pads on the transparent substrate are all located within an orthographic projection of the first metal light-shielding layer on the transparent substrate. The light-emitting devices are disposed on a side of the wiring layer away from the transparent substrate, and electrically connected to some of the pads; and orthographic projections of the light-emitting devices on the transparent substrate are located within the orthographic projection of the first metal light-shielding layer on the transparent substrate.
