Abstract:
1. A light-emitting device comprising: a first electrode and a second electrode over an insulating layer; a partition between the first electrode and the second electrode, the partition positioned over the insulating layer; a projecting object over the partition; a first light-emitting unit over the first electrode, the partition, the projecting object, and the second electrode; an intermediate layer over the first light-emitting unit; a second light-emitting unit over the intermediate layer; and a third electrode over the second light-emitting unit, wherein a recess is formed by a side surface of the projecting object and a side surface of the partition, wherein a distance between a first point and a second point is greater than a total thickness of the first light-emitting unit and the intermediate layer which are positioned over the first electrode and is smaller than or equal to a total thickness of the first light-emitting unit, the intermediate layer, the second light-emitting unit, and the third electrode which are positioned over the first electrode, wherein the first point is the most protruded point of the projecting object in a direction parallel to a surface on which the partition is formed, and wherein the second point is a point of intersection of a surface of the partition with a first line which is drawn perpendicular to the surface on which the partition is formed from the first point.
