Title:
LIGHT-EMITTING ELEMENT AND METHOD FOR MANUFACTURING LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/070120
Kind Code:
A1
Abstract:
The present invention pertains to a light-emitting element having a transparent substrate bonded to a light-extraction surface side thereof, the light-emitting element being characterized in that a transparent film, having a refractive index lower than that of the transparent substrate, is provided on the outer surface on the light-extraction surface side of the transparent substrate, and the outer surface of the transparent film is roughened. Consequently, there is provided: the light-emitting element formed by bonding the transparent substrate, wherein a light distribution angle is increased and a luminous efficiency is increased; and a method for manufacturing the light-emitting element.
