LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME

A light-emitting device includes: an OLED substrate including a structure wherein at least one blue emission unit and at least one green emission unit are stacked in the structure, and wherein the OLED substrate emits blue light and green light; and a color control unit located in a path of light emitted from the OLED substrate, wherein at least one green emission unit includes a first compound and a second compound, the first compound emits first light having a first spectrum, and λP(1) is a first emission peak wavelength, the second compound emits second light having a second spectrum, and λP(2) is a second emission peak wavelength, an absolute value of the difference between λP(1) and λP(2) is from 0 nanometer to about 30 nanometer, and λP(1) and λP(2) are each independently from about 500 nanometer to about 570 nanometer.
