Abstract
This invention aims to provide a white light emission diode arranged so that t rays emitted from an exciting element comprising a n-type semiconductor layer and a p-type semiconductor layer are converted by a wavelength converting element to white light which is then irradiated through molded resin. The white light emission diode offers a high color rendering effect desired for liquid crystal back light and minimizes deterioration of the molded resin to improve its light emission life characteristic. The wavelength converting element is provided on one surface of the exciting element and an insulating film is deposited on the other surface with interposition of a p-type ohmic electrode exhibiting a high reflectivity in UV wavelength band. The exciting element has its side surface covered with a n-type ohmic electrode exhibiting a high reflectivity in UV wavelength band.
