An electroluminescence display device includes a pixel electrode; a first organic layer provided on the pixel electrode; a light emitting layer provided on the first organic layer; a second organic layer provided on the light emitting layer; and a counter electrode provided on the second organic layer. The light emitting layer includes a host material, a light emitting dopant material and an assist dopant material. The light emitting dopant material has a first concentration distribution in a thickness direction of the light emitting layer; the assist dopant material has a second concentration distribution in the thickness direction of the light emitting layer; and the first concentration distribution has a concentration peak in a range of the second concentration distribution.
