Abstract
A display substrate includes a substrate, light-emitting devices disposed on a side of the substrate, a first light dimming layer disposed on the side of the substrate, and a first fixing layer disposed on a side of the light-emitting devices and the first light dimming layer away from the substrate. The light-emitting devices are arranged at intervals from each other and divided into a plurality of groups of light-emitting devices, and each group of light-emitting devices includes at least one light-emitting device. The first light dimming layer includes portions each located between two adjacent groups of light-emitting devices, and a gap exists between a portion of the first light dimming layer and at least one side face of at least one light-emitting device adjacent thereto. A portion of the first fixing layer is located in the gap. The first fixing layer is a light-transmitting film.
