Abstract: An electroluminescent display device includes a substrate having an emission area and a transparent portion, the emission area including a sub-pixel, and the transparent portion being adjacent to the sub-pixel; a first electrode in the emission area and over the substrate; a transparent connection pattern in the transparent portion and over the substrate, the transparent connection pattern being spaced apart from the first electrode; a first bank covering an edge of the first electrode and exposing the transparent connection pattern in the transparent portion; and a second bank on the first bank and covering the transparent connection pattern in the transparent portion, wherein the second bank includes a transparent conductive material.
