Abstract
A display substrate includes a first base, a plurality of light-emitting devices disposed on a side of the first base, a light dimming layer located in gaps between the plurality of light-emitting devices and located on surfaces of the plurality of light-emitting devices away from the first base, and a second base covering the light dimming layer. The plurality of light-emitting devices are spaced apart from each other. At least one light-emitting device is surrounded by the light dimming layer, a material of a portion, located in the gaps between the plurality of light-emitting devices, of the light dimming layer includes a light absorbing material, and the light dimming layer is configured to absorb part of light entering the light dimming layer.
