Abstract:
Disclosed is a light-emitting diode, which has a red and infrared emitting wavelength, excellent monochromatism characteristics, and high output and high efficiency and excellent humidity resistance. The light-emitting diode is provided with: a light-emitting section, which includes an active layer having a quantum well structure and formed by laminating alternately a well layer which comprises a composition expressed by the composition formula of (AlX1Ga1-X1)As (0≦X1≦1) and a barrier layer which comprises a composition expressed by the composition formula of (AlX2Ga1-X2)As (0
