Abstract
A display device includes a substrate, a via-insulating layer on the substrate, a first pixel electrode on the via-insulating layer, a first pixel defining layer having a flat upper surface, on the via-insulating layer, and defining an opening exposing at least a portion of an upper surface of the first pixel electrode, and separators on the first pixel defining layer and spaced apart from each other in a plan view.
Claims20
A display device comprising:
- a substrate;
- a via-insulating layer on the substrate;
- a first pixel electrode on the via-insulating layer;
- a first pixel defining layer having a flat upper surface, on the via-insulating layer, and defining an opening exposing at least a portion of an upper surface of the first pixel electrode;
- and
- separators on the first pixel defining layer and spaced apart from each other in a plan view.

A method for manufacturing a display device, the method comprising:
- forming a via-insulating layer on a substrate;
- forming a first pixel electrode on the via-insulating layer;
- forming a first preliminary layer defining a groove on the via-insulating layer and the first pixel electrode;
- forming a second preliminary layer that fills the groove on the first preliminary layer;
- forming a second portion of a first pixel defining layer that fills the groove and has a flat upper surface by removing a portion of the second preliminary layer;
- forming separators spaced apart from each other in a plan view on the second portion of the first pixel defining layer;
- and
- forming a first portion of the first pixel defining layer that defines an opening exposing at least a portion of an upper surface of the first pixel electrode and has a flat upper surface by patterning the first preliminary layer.
