WHITE LIGHT EMITTING DIODE

摘要

PURPOSE: A white light emitting diode is provided to prevent the effect of the inconsistency of a lattice constant with respect to a substrate by forming a light emitting unit into a nano-structure. CONSTITUTION: A first electrode(12) is formed on a substrate(11). An epi layer(18) is formed on the first electrode. A plurality of nano-rod shape light emitting units(16) is formed on the epi layer. A transparent electrode layer(17a) is formed to cover the outer surface of the light emitting units. An insulating layer(19) is interposed between the transparent electrode layer and the epi layer. A second electrode(17b) is formed on one side of a white light emitting diode(10) to electrically connect with the transparent electrode layer.
