Abstract

A display device includes a substrate, a thin-film transistor disposed on the substrate, a via insulating layer disposed above the thin-film transistor, a first electrode disposed on the via insulating layer and electrically connected to the thin-film transistor, a pixel-defining layer disposed on the via insulating layer and on the first electrode and that includes an opening that partially exposes an upper surface of the first electrode; and a first swelling prevention layer disposed on one end of the upper surface of the first electrode and interposed between the first electrode and the pixel-defining layer. The pixel-defining layer comprises a first region that overlaps the first swelling prevention layer and the first electrode, and a second region that overlaps the first electrode but not the first swelling prevention layer. The second region of the pixel-defining layer is in direct contact with the upper surface of the first electrode.
