发明名称 LIGHT EMITTING DEVICE
摘要 According to the invention, a Group III nitride compound semiconductor light-emitting element is provided with a light-emitting layer comprising two layers of different in ratio of AlGaInN composition, and emitting light with an emission peak wavelength in an ultraviolet region and light with an emission peak wavelength in a visible region. The light-emitting element and a fluorescent material excited by light in the ultraviolet region are combined to configure a light emitting device. <IMAGE>
