A LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting device is provided to improve the light extraction efficiency of a light emitting device by forming a plasmon layer which emits light by a surface plasmon resonance on the surface of a light emitting structure to suppress internal total reflection. CONSTITUTION: A light emitting structure(120) is located on a substrate(110) and includes a first conductive type semiconductor layer(122), an active layer(124), and a second conductive type semiconductor layer(126). A plasmon layer(130A) is formed on the second conductive type semiconductor layer. A conductive layer(140) is formed on the Plasmon layer. A first electrode(152) is formed on the first conductive type semiconductor layer. A second electrode(154) is formed on the conductive layer.
