摘要:
A light-emitting apparatus includes a plurality of light-emitting devices which are connected in series and formed by alternately disposing electrodes and organic layers including a light-emitting material, wherein the electrodes include one electrode and another electrode disposed at an anode end and a cathode end of the light-emitting devices, respectively, and an intermediate electrode disposed between two of the organic layers which serves as a cathode of the light-emitting device disposed on a side of the anode end and as an anode of the light-emitting device disposed on a side of the cathode end; the intermediate electrode is connected to a drive circuit having two current output terminals connected in common; the drive circuit receives data signals concerning two of the plurality of light-emitting devices for which the intermediate electrode serves as the anode and the cathode, respectively; and the drive circuit outputs currents which are different in direction from each other from the two current output terminals in response to the received data signals.
