Document Type and Number:
WIPO Patent Application WO/2014/178288
Kind Code:
A1
Abstract:
Provided is an ultraviolet light-emitting device that has high quality and high reliability and that prevents deterioration of electrical characteristics that is caused by a sealing resin and that results from ultraviolet light emission operation. The ultraviolet light-emitting device is provided with an ultraviolet light-emitting element (2) that comprises a nitride semiconductor and an ultraviolet light-transmissive sealing resin (3) that covers the ultraviolet light-emitting element (2). A specific part (3a) within the sealing resin (3) that at least comes into contact with pad electrodes (16, 17) of the ultraviolet light-emitting element (2) is a first type of amorphous fluorine resin, and the terminal functional group of the polymer or copolymer that constitutes the first type of amorphous fluorine resin is a non-reactive terminal functional group that does not bond with the metal that constitutes the pad electrodes (16, 17).
