LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE, AND METHOD OF PROCESSING SAPPHIRE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To improve light extraction efficiency of a light emitting element.

SOLUTION: This light emitting element is formed by forming a light emitting part on a principal surface of a substrate formed of sapphire. The light emitting element includes a side face 1a inclined to move away from a peripheral line 1b of the principal surface to the outside of the principal surface as it separates in a direction orthogonal to the principal surface.
