1. A display device comprising:
a substrate having a first region and a second region;
an anode at the first region;
an organic layer at the second region and at the anode of the first region;
a cathode on the organic layer of the first region;
an optical compensation layer on the cathode of the first region and the organic layer of the second region, and including at least one layer having a lower refractive index than a refractive index of the organic layer; and
an encapsulation layer on the optical compensation layer at the first region and the second region,
wherein the optical compensation layer directly contacts the organic layer over the second region, while the cathode is interposed between the optical compensation layer and the organic layer over the first region.
