An electroluminescent display device includes: a substrate, a first electrode on the substrate, a connection pattern on the substrate, the connection pattern including a same material as the first electrode, a bank covering edges of the first electrode and the connection pattern, a light-emitting layer on the first electrode, a second electrode on the light-emitting layer, the bank, and the connection pattern, and an auxiliary pattern between the connection pattern and the second electrode, the auxiliary pattern including one or more of: a metal oxide, conductive nanoparticles, and a work function-modifying polymer.

Electroluminescent display device including an auxiliary pattern between a connection pattern and a second electrode

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.
