Summary:A display device includes a base substrate; a thin-film transistor disposed on the base substrate; a via layer disposed on the thin-film transistor and having a via hole formed therein, the via hole penetrating the via layer in a thickness direction; a first electrode disposed on the via layer and having an electrode hole formed therein, the electrode hole penetrating the first electrode in the thickness direction; a bank layer disposed on the first electrode and exposing part of a top surface of the first electrode; an emission layer on the first electrode; and a second electrode on the emission layer, wherein the first is electrically connected to the thin-film transistor through the via hole, and the bank layer includes an outer bank pattern, which overlaps with the via hole in the thickness direction, and a bank island pattern, which is disposed in the electrode hole.
