Abstract
A display device includes a pixel electrode, a pixel defining layer including an opening extending to a portion of the pixel electrode, a first auxiliary electrode on the portion of the pixel electrode to which the opening extends, a second auxiliary electrode on the first auxiliary electrode, an intermediate layer on the pixel defining layer and the second auxiliary electrode, and a common electrode on the intermediate layer. A side surface of the first auxiliary electrode is positioned inward of a side surface of the second auxiliary electrode within the opening of the pixel defining layer to form an undercut shape. A hole injection layer of the intermediate layer includes a first portion on a side surface of the pixel defining layer defining the opening of the pixel defining layer, and a second portion disconnected from the first portion and on the second auxiliary electrode.
