White light emission diode

A white light emission diode comprising:

• an exciting element for emitting UV rays, the exciting element including a p-type semiconductor layer and an n-type semiconductor layer and defining a contact region between the p-type semiconductor layer and the n-type semiconductor layer;
• a wavelength converting element for converting the UV rays emitted by the exciting element to white wavelength light rays by means of fluorescence, the wavelength converting element being disposed on a first surface of the exciting element extending in parallel to the contact region;
• an insulating film formed on a side surface of the exciting element over an area where the contact region intersects the side surface, the insulating film being transparent in the UV wavelength band and a vicinity thereof;
• a p-type ohmic electrode and an n-type ohmic electrode both having high reflectivity in the UV wavelength band and a vicinity thereof, the p-type ohmic electrode and the n-type ohmic electrode being disposed to cover at least a majority of the surface of the exciting element other than the first surface;
• and
• a transparent molded resin covering the exciting element, the wavelength converting element, the insulating film, the p-type ohmic electrode and the n-type ohmic electrode.
