An electroluminescent display device comprising:
- a first pixel and a second pixel, wherein each of the first pixel and the second pixel includes a first sub pixel configured to emit first colored light, a second sub pixel configured to emit second colored light, and a third sub pixel configured to emit third colored light;
- a first electrode in each of the first sub pixel, the second sub pixel, and the third sub pixel;
- an emission layer on the first electrode;
- a second electrode on the emission layer;
- and
- a charge blocking layer including a first charge blocking layer provided in an area overlapped with a boundary area between the first sub pixel of the first pixel and the first sub pixel of the second pixel, a second charge blocking layer provided in an area overlapped with a boundary area between the second sub pixel of the first pixel and the second sub pixel of the second pixel, and a third charge blocking layer provided in an area overlapped with a boundary area between the third sub pixel of the first pixel and the third sub pixel of the second pixel.
