Abstract: A display device includes first to fourth electrodes spaced from each other on a base surface and a fifth electrode spaced from the first to fourth electrodes. A first light emitter is between the first to fourth electrodes and the fifth electrode and overlaps the first to fourth electrodes. A second light emitter is between the fourth and fifth electrodes and overlaps at least one of the first or second electrodes. A third light emitter is between the first to fourth electrodes and the fifth electrode and overlaps at least one of the third or fourth electrodes. A charge generating is layer between the first and second light emitters and between the first and third light emitters. Color filters transmit light from the light emitters in different wavelength ranges.
