Abstract

An electroluminescent display device can include a substrate (100) including a first sub-pixel (R Sub-pixel) and a second sub-pixel (G Sub-pixel), a first electrode (400) in each of the first sub-pixel (R Sub-pixel) and the second sub-pixel (G Sub-pixel) on the substrate (100), a light emitting part (500) on the first electrode (400), and a second electrode (600) on the light emitting part (500). The light emitting part (500) includes a hole transport layer (HTL1, HTL2-2(R)), HTL2-1(G)), a first light emitting layer (EML(R)) disposed in the first sub-pixel (R Sub-pixel), a second light emitting layer (EML(G)) disposed in the second sub-pixel (G Sub-pixel), and an electron transport layer (ETL). The second light emitting layer (EML(G)) extends to the first sub-pixel (R Sub-pixel) and is disposed under the first light emitting layer (EML(R)). The hole transport layer (HTL1, HTL2-2(R)), HTL2-1(G)) is disposed between the second light emitting layer (EML(G)) and the first light emitting layer (EML(R)) in the first sub-pixel (R Sub-pixel).
