Abstract: An electronic device including: a base layer; a circuit layer on the base layer, the circuit layer including pixel drive circuits and an insulating layer covering the pixel drive circuits; and a light emitting element layer on the circuit layer, the light emitting element layer including light emitting elements respectively electrically connected to the pixel drive circuits. The light emitting elements include first through third light emitting elements respectively including first through third pixel electrodes. The insulating layer has first through third upper surface portion respectively overlapping the first through third pixel electrodes, and degrees of flatness of the first, second, and third upper surface portions differ from one another.

Abstract: Disclosed is a display panel which includes a base layer having a hole, a circuit layer disposed on the base layer and including a pixel circuit and a plurality of insulating layers, an element layer disposed on the circuit layer and including a light emitting element electrically connected to the pixel circuit and a pixel defining layer defining an emissive region, and an encapsulation layer covering the element layer. The circuit layer further includes a groove surrounding the hole, and the pixel defining layer includes a valley surrounding at least a portion of the emissive region. A bottom surface of the groove and side surfaces of the groove connected to the bottom surface are formed by an insulating layer among the plurality of insulating layers.
