An electroluminescence (EL) display device with improved external light coupling efficiency and brightness that may be easily manufactured. The EL display device includes: a substrate; a first electrode arranged above the substrate; a second electrode arranged above and substantially parallel to the first electrode; an intermediate layer arranged between the first and second electrodes, and including an emissive layer; a color converting layer arranged between the substrate and the first electrode or above the second electrode; and a light resonance controlling layer arranged between the emissive layer and the color converting layer.
