    摘要: 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, 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.
