Claim 4:
5. A display device comprising:
a base substrate comprising a first sub-pixel area, a second sub-pixel area, and a third sub-pixel area;
first to third thin film transistors on the base substrate and comprising first to third active patterns, respectively;
first to third pixel electrodes electrically connected to the first to third thin film transistors, respectively, and in the first to third sub-pixel areas, respectively;
a blue light emitting layer on the first to third pixel electrodes and configured to emit a blue light;
a first color conversion pattern in the first sub-pixel area on the blue light emitting layer;
a second color conversion pattern in the second sub-pixel area on the blue light emitting layer; and
a red color filter layer between the blue light emitting layer and the first to third active patterns;
a first color filter on the first color conversion pattern;
a second color filter on the second color conversion pattern;
a transmissive pattern in the third sub-pixel area on the blue light emitting layer;
a third color filter on the transmissive pattern;
a counter substrate facing the base substrate;
a first insulating layer between the counter substrate and the first color conversion pattern, between the counter substrate and the second color conversion pattern, and between the counter substrate and the transmissive pattern, the first insulating layer comprising an inorganic insulating material; and
a second insulating layer between the blue light emitting layer and the first color conversion pattern, between the blue light emitting layer and the second color conversion pattern, and between the blue light emitting layer and the transmissive pattern, the second insulating layer comprising an inorganic insulating material,
wherein the first color conversion pattern is at least one selected from among red quantum dot particles and red phosphors, and
wherein the second color conversion pattern is at least one selected from among green quantum dot particles and green phosphors.
