Abstract
A display device includes a thin-film transistor, a source/drain electrode and an auxiliary electrode including a first conductive layer and a second conductive layer disposed on the first conductive layer, a via insulating layer having a first opening exposing the auxiliary electrode, a capping layer covering a portion of the auxiliary electrode and a light emitting material layer and a common electrode layer sequentially stacked on the via insulating layer and the capping layer, wherein the source/drain electrode is electrically connected to the thin-film transistor through a contact hole penetrating the interlayer insulating layer, the auxiliary electrode has an undercut, and the capping layer includes a first capping layer covering side surfaces of the first conductive layer of the auxiliary electrode and a second capping layer separated from the first capping layer and disposed on the second conductive layer of the auxiliary electrode.
