Abstract: A display device includes a base layer including an active area and a peripheral area outside the active area, a circuit element layer including a pixel in the active area of the base layer, a light emitting element layer including light emitting elements on the circuit element layer, a thin film encapsulation layer covering the light emitting element layer and including an organic layer, and an input detection layer on the thin film encapsulation layer and including a detection electrode and a detection wire connected to the detection electrode. The circuit element layer includes a connection wire overlapping the detection wire in the peripheral area, and a contact part to connect the detection wire and the connection wire in the peripheral area. The contact part is spaced apart from the organic layer of the thin film encapsulation layer on a plane.
