An organic electroluminescent display device, comprising:

• a first pixel region including a first red sub-pixel region, a first green sub-pixel region and a first blue sub-pixel region, wherein the first red and green sub-pixel regions are positioned at a first side of the first blue sub-pixel region;
• a first red emitting area in the first red sub-pixel region;
• a first green emitting area in the first green sub-pixel region;
• and
• a first blue emitting area in the first blue sub-pixel region,
• wherein the first red emitting area has a first shape having a first vertical length and a first horizontal length being larger than the first vertical length, and the first green emitting area has a second shape having a second vertical length and a second horizontal length being larger than the second vertical length,
• wherein the first blue emitting area has a third shape having a third horizontal length and a third vertical length being larger than the third horizontal length, and
• wherein the third horizontal length is smaller than each of the first horizontal length and the second horizontal length.
