Classification: CPC H | IPC H

Claim 15:
16. A display device comprising:
a first sub-pixel configured to emit a red light;
a second sub-pixel configured to emit a green light; and
a third sub-pixel configured to emit a blue light,
wherein the first sub-pixel comprises a first thin film transistor, a first pixel electrode electrically connected to the first thin film transistor, a first blue light emitting layer, and a red color conversion pattern on the first blue light emitting layer,
wherein the second sub-pixel comprises a second thin film transistor, a second blue light emitting layer, and a green color conversion pattern on the second blue light emitting layer,
wherein the third sub-pixel comprises a third thin film transistor and a third blue light emitting layer, and
wherein the display device further comprises a red color filter layer between the first thin film transistor and the first blue light emitting layer, between the second thin film transistor and the second blue light emitting layer, and between the third thin film transistor and the third blue light emitting layer, and
wherein, in a plan view, an area, in which the first blue light emitting layer overlaps the first pixel electrode, defines a first light emitting area, and
wherein the red color filter layer overlaps the defined first light emitting area in the plan view.
