Abstract

A display device includes a substrate including emission non-emission areas; an anode electrode on the emission area of the substrate; a pixel defining layer on the anode electrode and overlapping the non-emission area, with a first opening defined therethrough; a first bank structure on the pixel defining layer, and including at least two conductive materials, with a second opening defined therethrough; a second bank structure on the first bank structure and including at least two materials; and a first encapsulation layer on the second bank structure, where the first bank structure includes a first bank layer and a second bank layer including a first tip protruding toward a center of the first opening, the second bank structure includes a third bank layer and a fourth bank layer including a 10 second tip protruding toward a center of the second opening, and the first encapsulation layer covers the first and second tips.
