Beschreibung
Zusammenfassung:	A surface light source device includes: a plurality of light-emitting devices, each of the plurality of light-emitting devices including a light-emitting element disposed on a substrate and configured to emit light with a wavelength of 380 to 485 nm and a light flux controlling member disposed over the light-emitting element and configured to control a distribution of light emitted from the light-emitting element; and an optical sheet including a wavelength conversion sheet disposed over the light flux controlling member and configured to convert a wavelength of incident light. The light flux controlling member is formed with a resin composition or a glass composition containing a scattering member, and makes scattering of light with a wavelength longer than the wavelength of 380 to 485 nm large.
