Abstract: A display device includes: a substrate; an organic insulating layer on the substrate and having an opening; a first electrode on the organic insulating layer; an auxiliary electrode on the organic insulating layer and including a first portion overlapping the opening; a bank layer having a first bank opening overlapping the first electrode and a second bank opening overlapping the first portion; an intermediate layer on the first electrode and the auxiliary electrode, the intermediate layer including a hole exposing a portion of the auxiliary electrode; and a second electrode on the intermediate layer, overlapping the first electrode and the auxiliary electrode, and in contact with the auxiliary electrode through the hole in the intermediate layer. The hole in the intermediate layer only partially overlaps the opening in the organic insulating layer and is located within the second bank opening in a plan view.
