Abstract
An electroluminescent display device can include a plurality of sub-pixels arranged on a substrate along a first direction and a second direction; a light-emitting diode disposed at each sub-pixel and including a first electrode, a light-emitting layer and a second electrode; a first bank disposed between adjacent sub-pixels along the second direction and overlapping edges of the first electrode; a second bank having an opening corresponding to the sub-pixels arranged along the second direction and disposed between adjacent sub-pixels along the first direction; and a third bank on side surfaces of the second bank facing each other along the second direction.
