PROBLEM TO BE SOLVED: To provide an organic electroluminescence display device having each pixel of at least red (R), green (G) and blue (B), wherein green chromaticity is enhanced to improve the green reproducibility. SOLUTION: The organic electroluminescence display device is equipped with an organic EL light emitting layer 9 which emits white light, a hole injection electrode 2, an electron injection electrode 8, color filter layers CFR and CFB of the red and the blue disposed on the photoirradiation side of the organic EL light emitting layer, wherein the organic EL light emitting layer 9 is placed between the hole injection electrode 2 and the electron injection electrode 8, and the organic EL light emitting layer 9 has such a structure that a blue light emitting layer 6 containing a host material and arranged on the electron injection electrode side, and an orange light emitting layer 4 containing a host material and arranged on the hole injection electrode side, are laminated, and a green light emitting layer 5 containing the host material is disposed between the blue light emitting layer 6 and the orange light emitting layer 4 in a region of a green pixel.
