Abstract

PURPOSE: To readily identify polarity by disposing a light emitting diode having full face electrodes on both main surfaces parallel to a PN junction in such a manner that the PN junction face becomes perpendicular to substrate surface and identifying the brightness and darkness at both ends of the pellet.
