Abstract: An electroluminescent display device includes a substrate including a first pixel column and a second pixel column that respectively include first pixels and second pixels arranged in a first direction and respectively have a first width and a second width in a second direction, wherein the second pixel column is positioned in the second direction from the first pixel column, and the second width is greater than the first width; a light emitting diode in each first pixel and each second pixel and including a first electrode, a light emitting layer and a second electrode; a first bank positioned between adjacent first pixels and between adjacent second pixels and covering an edge of the first electrode; a second bank positioned between the first and second pixel columns; and a first partition wall across the second pixel column along the first direction and positioned on the first electrode.
