Abstract

The present disclosure provides a display device and a method of manufacturing the same. A display device includes a common electrode and a pixel electrode spaced from each other on a substrate, a bank having an opening exposing a portion of the pixel electrode and the common electrode, a first reflective electrode on a top surface of the bank along the opening on a top surface of the pixel electrode, and a second reflective electrode on a top surface of the bank along the opening on a top surface of the common electrode, an organic pattern layer on the pixel electrode and the common electrode in the opening, a light emitting element on the organic pattern layer and including a first contact electrode and a second contact electrode on a top surface, and a first via layer having a height that is less than that of the light emitting element.
