A display device includes a cathode disposed on a pixel circuit layer, a first anode, a first light-emitting element including a first emission stack, a first anode connection electrode, a first cathode connection electrode, an adhesive layer disposed between the first anode and the first anode connection electrode and between the cathode and the first cathode connection electrode, a first anode bridge electrode in contact with the first anode and the first anode connection electrode, and a cathode bridge electrode in contact with the cathode and the first cathode connection electrode. A planarization layer forming an uppermost layer of the pixel circuit layer includes a first anode undercut formed along an edge of the first anode between the planarization layer and a lower surface of the first anode, and a cathode undercut formed along an edge of the cathode between the planarization layer and a lower surface of the cathode.
