1. A display device comprising:
a substrate comprising a pixel area and a transmission area, the pixel area with an emission layer therein, the emission layer being to emit light;
a plurality of insulating layers in the pixel area and the transmission area;
a first conductive layer on the plurality of insulating layers in the pixel area, the first conductive layer comprising a first sidewall having a first inclination angle and a second sidewall having a second inclination angle different from the first inclination angle;
a first spacer located on a same layer as the first conductive layer, the first spacer being at a boundary between the pixel area and the transmission area and extending to the pixel area and the transmission area; and
a first planarization layer on the first conductive layer,
wherein the first inclination angle is greater than the second inclination angle;
wherein the first sidewall and the second sidewall are opposite and lateral ends of the first conductive layer;
wherein the first spacer does not overlap the emission layer in a thickness direction of the display device; and
wherein the first spacer comprises an inorganic insulating material.
