Abstract

PURPOSE:To obtain stable performance and reliable operation by a method wherein films are provided on etched planes to isolate a P-N junction from the air. CONSTITUTION:The array of mesa-shaped light emitting diodes 13 is formed on a substrate 1 in a light emitting diode device 12. The side of each light emitting diode 13, namely, etched planes are coated by films 10. Therefore, a P-N junction formed between a one conductivity layer 2 and a reverse conductivity-type layer 3 is not exposed to the outside. So performance is stabilized. An upper electrode 6 and a lower electrode 7 are formed on each light emitting diode.
