1. A display device, comprising:
a substrate;
a via insulating layer disposed on the substrate;
a first lower electrode disposed on the via insulating layer; and
a second lower electrode disposed on the via insulating layer, wherein the second lower electrode has a shape different from a shape of the first lower electrode,
wherein the first lower electrode includes a first transparent electrode, a first reflective electrode, and a second transparent electrode,
wherein the second lower electrode includes a third transparent electrode, a second reflective electrode, and a fourth transparent electrode,
wherein the first transparent electrode overlaps a first central region of the first lower electrode and a first peripheral region, which is surrounding the first central region, of the first lower electrode,
wherein the first reflective electrode is disposed on the first transparent electrode and overlaps the first central region,
wherein the second transparent electrode is disposed on the first reflective electrode and overlaps the first central region, wherein the first reflective electrode and the second transparent electrode do not cover a portion of a top surface of the first transparent electrode,
wherein the third transparent electrode overlaps a second central region of the second lower electrode and a second peripheral region, which is surrounding the second central region, of the second lower electrode,
wherein the second reflective electrode is disposed on the third transparent electrode and overlaps the second central region, and
wherein the fourth transparent electrode is disposed on the second reflective electrode and overlaps the second central region.
