Abstract: Disclosed is a display device. In the disclosed display device, an emission-side electrode is constituted by a transmissive electrode structure having different configurations for an emission part and a transmission part such that a uniform potential is maintained at the entirety of the transmissive electrode structure, and the transmissive electrode structure enables the emission part to emit light at high brightness while enabling the transmission part to perform transparent display at high transmissivity.
