Abstract
An organic light-emitting structure is described. The organic light-emitting structure includes a first light-emitting unit, a second light-emitting unit, a third light-emitting unit, and a fourth light-emitting unit. Each of the first light-emitting unit, the second light-emitting unit, the third light-emitting unit, and the fourth light-emitting unit comprises a first electrode, a second electrode, and an organic laminated body placed between the first electrode and the second electrode. One of the first electrode and the second electrode is a translucent electrode. At least one light-emitting unit is a fluorescent light-emitting unit. The color gamut range of the organic light-emitting structure is increased, the color saturation of the light-emitting device is improved, and quantity of colors is increased, so that the development trend of color reproducibility for the display devices can be satisfied.
