Abstract: The present invention relates to a light-emitting diode having enhanced liability. More particularly, a light-emitting diode has enhanced liability in a high-temperature and/or high humidity environment as well as in a room-temperature environment and can have decrease in light-emitting characteristics prevented. In addition, the present invention relates to a light-emitting diode comprising a structure which enables enhancing of light reflection and having enhanced light extraction efficiency by means of light reflection through the structure.
