Zusammenfassung: | Provided are a light-emitting device and an electronic apparatus including the same, the light-emitting device comprising: an organic light-emitting device (OLED) substrate having a structure in which at least one blue light-emitting unit and at least one green light-emitting unit are stacked, and which generates light in which blue light and green light are mixed; and a color control unit arranged on a path through which the light emitted from the OLED substrate passes, so as to adjust a color of the light generated from the OLED substrate, wherein at least one of the green light-emitting units includes a mixture of a first compound and a second compound, the first compound and the second compound are different from each other, the first compound is capable of emitting first light having a first spectrum, λP(1) represents a light-emitting peak wavelength (nm) of the first spectrum, the second compound is capable of emitting second light having a second spectrum, λP(2) represents a light-emitting peak wavelength (nm) of the second spectrum, an absolute value of a difference between λP(1) and λP(2) is 0 nm to 30 nm, and each of λP(1) and λP(2) is 500 nm to 570 nm. Accordingly, the light-emitting device has high luminous efficiency and a long lifespan, so that it is possible to provide high-quality electronic devices using the same.
