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: Provided is a display device according to an embodiment including a display panel including a display region and a non-display region, and an input sensing unit disposed on the display panel, wherein the input sensing unit includes a first sensing insulating layer disposed on the display panel, and a first sensing conductive layer disposed on the first sensing insulating layer, and the first sensing insulating layer has an atomic ratio of nitrogen (N) to silicon (Si) of about 0.69 to about 0.85. Accordingly, corrosion of the electrode and wires due to the electric field when the input sensing unit is driven may be controlled. Accordingly, reliability of the display device may be improved.
