Patent attributes
An organic light-emitting device and a display device are disclosed. The organic light-emitting device includes a substrate layer, a first electrode layer, a light-emitting layer, a second electrode layer which are stacked; and a first barrier layer disposed between the first electrode layer and the light-emitting layer, a second barrier layer disposed between the second electrode layer and the light-emitting layer, wherein, each of the first and second barrier layers includes a light-emitting host material, a triplet energy level T1 of the light-emitting host material ≥2.5 ev. Because the organic light-emitting device is disposed with first and second barrier layers including the light-emitting host material, the structure of the light-emitting device can increase the lifetime and the luminous efficiency of the organic light-emitting device.
