Abstract: A display device is disclosed that includes: pixels each including emission areas and a non-emission area adjacent to the emission areas, and a pixel defining layer overlapping the non-emission area. The pixel defining layer includes trenches enclosing the respective emission areas and spaced apart from each other. A corner of each of the trenches is chamfered.
