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 circuit in the active area and a driving voltage wiring located in the peripheral area to supply a driving voltage to the pixel circuit. A light emitting element layer including a plurality of light emitting elements on the circuit element layer, a thin film sealing layer to cover the light emitting element layer, and an input sensing layer on the thin film sealing layer and including a sensing electrode and a sensing signal wiring part connected to the sensing electrode. The circuit element layer includes a connection wiring part overlapping the driving voltage wiring in the peripheral area and contacts the sensing signal wiring part. The connection wiring part is at a different layer from the driving voltage wiring.
