Abstract: A light emitting element comprises: a substrate including protrusions; and a light emitting structure located on the substrate. The protrusions are disposed in a honeycomb pattern and include a first protrusion and second to seventh protrusions which are adjacent to the first protrusion and spaced equidistant from the first protrusions. The angle between a first vector line extending in a direction from the center of the first protrusion toward the center of the second protrusion and a second vector line extending in a direction from the center of the first protrusion to the center of the fourth projection is 120° , the angle between the second vector line and the third vector line extending in a direction from the center of the first projection to the center of the sixth protrusion is 120.
