Abstract: A display device having a light-emitting device is provided. The display device can include a buffer insulating layer disposed on a path of light emitted from the light-emitting device. The buffer insulating layer can have a stacked structure of a first buffer insulating layer having the refractive index which decreases in a direction away from the light-emitting device, and a second buffer insulating layer having the refractive index which increases in a direction away from the light-emitting device. Thus, in the display device, the unintended constructive and destructive interference of the light emitted from the light-emitting device can be prevented. Therefore, in the display device, the luminous efficacy can be increased, and the variation of color coordinates can be prevented.

Abstract: An organic light-emitting diode display device includes a first electrode, a first stack emitting blue light, a first charge generation layer on the first stack; a second stack emitting yellow-green light, a second charge generation layer on the second stack, a third stack emitting blue light, and a second electrode on the third stack, wherein at least one of the first stack and the third stack further emits red light, wherein the at least one of the first stack and the third stack includes a first red emitting material layer and a blue emitting material layer, and wherein each of the first red emitting material layer and the blue emitting material layer includes a host and a dopant, and a T1 energy of the host of the blue emitting material layer is greater than a T1 energy of the dopant of the first red emitting material layer.
