1. A display device comprising:
a first pixel and a second pixel on a substrate, the first pixel has a relatively narrow viewing angle, and the second pixel has a relatively wide viewing angle, and
wherein the first pixel 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 in a plan view;
a light emitting element disposed between the pixel defining layer 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 comprising a light blocking pattern, wherein the light blocking pattern is disposed on the encapsulation layer and overlaps at least a portion of the dummy pixel defining layer in the plan view.
