Abstract
A display device includes a substrate, a via insulating layer disposed on the substrate and defining a groove, a lower electrode disposed on the via insulating layer and spaced apart from the groove in a plan view, a pixel defining layer disposed on the via insulating layer, defining an opening exposing at least a part of an upper surface of the lower electrode, and filling the groove, and a light-emitting layer disposed in the opening of the pixel defining layer.

A method for manufacturing a display device, the method comprising:
- forming a first preliminary layer on a substrate;
- forming a lower electrode on the first preliminary layer;
- forming a via insulating layer defining a groove by patterning the first preliminary layer using the lower electrode as a mask;
- forming a second preliminary layer on the lower electrode and the via insulating layer to cover the lower electrode and fill the groove;
- and
- forming a pixel defining layer defining an opening exposing at least a part of an upper surface of the lower electrode by patterning the second preliminary layer through a mask.
