Abstract
A display device, an optical device, and an electronic device are disclosed. The display device, optical device, and electronic device can minimize or reduce (or minimize or reduce the degree or incidence of) current reduction in a cathode contact area. The display device can include a substrate, a first electrode on the substrate, a pixel defining layer on the first electrode, an emission stack on the first electrode and the pixel defining layer, a second electrode on the emission stack, and a cathode pad connected to the second electrode in a cathode contact area of the substrate through a contact area defined by the pixel defining layer, where the cathode pad can be continuous without being broken in the contact area, thereby minimizing or reducing current reduction in a cathode contact area.
