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.
