LIGHT EMITTING DIODE AND LED ARRAY HEAD

摘要

PROBLEM TO BE SOLVED: To provide a high performance light emitting diode by improving light emitting directivity in the light emitting body. SOLUTION: A semiconductor buffer layer 2 is formed in a shape like an island on a single crystal substrate 1. A forward conductive semiconductor layer 3, a reverse conductive semiconductor layer 4, and an individual electrode 6 are sequentially formed on a semiconductor buffer layer 2 in the light emitting diode. The surrounding edge of the reverse conductive semiconductor layer 4 has an inclination with an inclination angle of 90 degrees or below to the single crystal substrate 1.
