Abstract

A display device includes a substrate; a pixel electrode disposed on the substrate; a pixel defining layer disposed on the substrate and defining a pixel opening exposing a portion of the pixel electrode; a dummy pixel defining layer disposed on the pixel electrode in the pixel opening, and spaced apart from the pixel defining layer; a light emitting element disposed between the pixel electrode and the dummy pixel defining layer in the pixel opening; a common electrode covering the pixel defining layer, the dummy pixel defining layer, and the light emitting element; an encapsulation layer covering the common electrode; and a touch sensing layer including a light blocking pattern, wherein light blocking pattern is disposed on the encapsulation layer and overlaps at least a portion of the dummy pixel defining layer in a plan view.
