    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.

    Abstract: A light-emitting device includes: a first electrode; a second electrode; m emission units between the first electrode and the second electrode; and m−1 charge generation layer(s), each located between two adjacent emission units, and including m−1 n-type charge generation layer(s) and m−1 p-type charge generation layer(s). The m emission units each include a hole transport region, an emission layer, and an electron transport region. A first hole transport region in a first emission unit closest to the first electrode may include a hole transfer layer and a hole injection layer and/or a hole transport layer. The hole transfer layer may be a single layer consisting of an electron-transporting compound including a phosphine oxide group (P═O), a phosphine sulfide group (P═S), a π electron-deficient nitrogen-containing C1-C60 cyclic group, or any combination thereof. A highest occupied molecular orbital (HOMO) energy level of the hole transfer layer may be about −6.0 eV to about −5.3 eV.
