DISPLAY SUBSTRATE AND DISPLAY APPARATUS

This abstract first appeared for US patent application 18728017 titled 'DISPLAY SUBSTRATE AND DISPLAY APPARATUS

Original Abstract Submitted

A display substrate and a display apparatus. The display apparatus comprises a base substrate and, disposed on the base substrate, a plurality of light-emitting elements and a pixel defining pattern. The light-emitting elements comprise a light-emitting functional layer, a first electrode and a second electrode; the pixel defining pattern comprises a plurality of openings and a defining part surrounding the plurality of openings, and the light-emitting elements are at least partially located in the openings. The light-emitting elements further comprise a light conversion layer, the light conversion layer being configured to cause one color of light incident upon the light conversion layer to then be emitted as a different color of light; the light conversion layer is located on the side of the second electrode away from the base substrate, and the light conversion layer is at least partially located in the openings; the surface, closest to the base substrate, of the part of the light conversion layer located in the openings is closer to the base substrate than at least a portion of the surface, furthest from the base substrate, of the defining part. The display substrate provided by the embodiments of the present disclosure reduces to the extent possible the distance between the light conversion layer and the light-emitting functional layer, so as to improve the conversion efficiency of incident light by the light conversion layer.
