Abstract: An electroluminescent display device can include a plurality of pixels arranged in a matrix form along a first direction and a second direction, each pixel including first, second, and third sub-pixels, and a first bank pattern having a first height, and a second bank pattern having a second height, the first height being smaller than the second height, wherein the second bank pattern is parallel in two directions. The first bank pattern defines same color sub-pixels of different pixels, and wherein the second bank pattern defines different color sub-pixels of the same pixel. The second bank pattern includes first patterns disposed between the adjacent different color sub-pixels along a third direction crossing the first and second directions and between the adjacent different color sub-pixels along a fourth direction crossing the first, second, and third directions and second patterns disposed between the second sub-pixels adjacent to each other.
