[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2013-147743 filed on Jul. 16, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to an electronic device, an optical disc device, a display device, and an imaging device having a protective film. Background technique [0004] In recent years, various laser diode elements (semiconductor light emitting elements) have been widely used as light sources for optical disk recording and reproducing apparatuses. Recently, as a light source for next-generation high-density optical discs with high recording density, there is an increasing demand for blue-violet laser diode elements using III-V nitride semiconductors such as gallium nitride (GaN). [0005] A protective film made of oxide is formed on the resonator end faces of these laser diode elements to prevent entry of ext...
