1. A display device comprising:
a display element layer including an emission area and a non-emission area around the emission area, the non-emission area including a pixel defining layer in which a pixel opening part defined and the emission area including a light emitting element disposed in the pixel opening part;
a first conductive layer on the pixel defining layer in the non-emission area;
a first insulating layer on the pixel defining layer in the non-emission area to cover the first conductive layer, the first insulating layer having an opening part overlapping the emission area in a plan view;
a second conductive layer directly on the first insulating layer; and
a reflection pattern spaced apart from the second conductive layer and on opposite side surfaces of the first insulating layer, wherein the second conductive layer is on a flat upper surface of the first insulating layer between the opposite side surfaces of the first insulating layer in a plan view, and
wherein the reflection pattern and the second conductive layer overlap the non-emission area and do not overlap the emission area when viewed on a plan, are coplanar, and separated from each other on the flat upper surface of the first insulating layer.
