Claims29
A light emitting element comprising:
- a semiconductor including an active layer,
- a planar shape of the light emitting element having a concave polygon when viewed in plan view, wherein the concave polygon has interior angles including at least one acute angle,
- wherein the planar shape of the light emitting element includes a shape obtained by dividing a hexagon having parallel opposite sides and two reentrant angles into two congruent concave polygons.
A light emitting element comprising:
- a semiconductor including an active layer,
- a planar shape of the light emitting element having a concave polygon when viewed in plan view, wherein the concave polygon has interior angles including at least one acute angle,
- wherein the planar shape of the light emitting element is so constructed that a cut part of a concave hexagon having parallel opposite sides is connected to a remaining part of the hexagon such that a side of the hexagon in the cut part corresponds to another side of the hexagon of the remaining part which was parallel to the side of the cut part before being cut.
A light emitting element array comprising:
- light emitting elements arranged to provide the light emitting element array,
- each of the light emitting elements including a semiconductor, the semiconductor including an active layer,
- at least one of the light emitting elements having a planar shape of a concave polygon when viewed in plan view, the concave polygon having interior angles including at least one acute angles,
- wherein the planar shape of the light emitting element is so constructed that a cut part of a concave hexagon having parallel opposite sides is connected to a remaining part of the hexagon such that a side of the hexagon of the cut part corresponds to another side of the hexagon in the remaining part which was parallel to the side of the cut part before being cut.
