1. A light-emitting apparatus comprising:
a first lower electrode;
a second lower electrode;
a functional layer covering the first lower electrode and the second lower electrode;
an upper electrode on the functional layer; and
a third lower electrode between the first lower electrode and the second lower electrode,
wherein the third lower electrode has an inclined portion inclined with respect to an upper surface of the first lower electrode,
wherein the third lower electrode, an insulating layer, the functional layer, and the upper electrode are arranged in this order in a direction perpendicular to the inclined portion,
wherein the first lower electrode, the second lower electrode, and the third lower electrode are electrically independent of each other, and
wherein a thickness of the functional layer at the inclined portion is less than a thickness of the functional layer at a point that the first lower electrode contacts the functional layer.
