Abstract: An electroluminescent display device which may improve display quality is discussed. The electroluminescent display device includes a substrate in which a plurality of pixel areas are defined, a first electrode arranged in each pixel area, a light emitting layer on the first electrode within the pixel area, and a second electrode on the light emitting layer. Particularly, a step difference portion is arranged at an edge of the pixel area, and is partially or fully be filled with the light emitting layer. Film uniformity of the light emitting layer within the pixel area may be improved by arrangement of the step difference portion.
