Abstract: Multiple first recesses are formed on the side of an inorganic insulating layer facing towards multiple LEDs. Orthographic projections of the first recesses on a driving substrate do not overlap orthographic projections of the LEDs on the driving substrate. Thus, when a first planarization layer covering the multiple LEDs is formed on the side of the multiple LEDs facing away from the driving substrate, the first recesses can be filled with the first planarization layer, so that a contact area between the first planarization layer and the inorganic insulating layer can be increased, a binding force between the first planarization layer and the inorganic insulating layer can be increased, and the risk of peeling off the first planarization layer can be reduced, thereby improving the stability of a QD-LED device.
