Light-emitting element, display substrate, and display device

The invention provides a light-emitting element, a display substrate and a display device. The light-emitting element comprises a substrate, a plurality of light-emitting structures, a filling layer, a connecting electrode layer, an insulating layer and a plurality of bonding pads, the plurality of light-emitting structures are located on the substrate; the filling and leveling layer is positioned among the plurality of light-emitting structures; the connecting electrode layer is located on one side of the filling layer away from the substrate; the insulating layer is located on one side of the connecting electrode layer away from the filling layer; the plurality of bonding pads are positioned on one side, far away from the connecting electrode layer, of the insulating layer; each light-emitting structure comprises a first pole and a second pole, the connecting electrode layer comprises a plurality of connecting electrodes, and each connecting electrode is connected with the first pole or the second pole of at least one light-emitting structure; the light-emitting element further comprises a plurality of holes located in the insulating layer, and the plurality of bonding pads are connected with the plurality of connecting electrodes through the plurality of holes. Therefore, the light-emitting element can improve and even avoid the defect of missing parts, and the die bonding efficiency is improved.
