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.

Abstract: An electronic device includes a display module including a base layer including a margin area and a pixel area, pixels, and a cover organic layer. A module hole through which the display module and the cover organic layer, which overlap the margin area, pass is defined, the margin area is divided into a first area, a second area, and a third area surrounding the module hole, and the display module includes dam patterns on at least one of the first area or the second area. Each of the dam patterns includes a first insulating pattern, a first pattern on the first insulating pattern, a second insulating pattern having an opening exposing at least a portion of the first pattern, a second pattern on the second insulating pattern and in contact with the first pattern through the opening, and a third insulating pattern covering the second pattern.
