The light flux controlling member includes an incident surface, an emission surface, a back surface, a protruding portion and a scattering portion. In a cross section including a central axis, an angle formed by two beams, which are emitted from the light emitting device and have a maximum luminous intensity, is 150° or more. In a cross section including a central axis, predetermined light is made incident at an incident angle of 60° and an average angle, which is formed by, among the light reflected by the scattering portion, a light ray having a maximum light amount and a light ray having a light amount of 50% of the maximum light amount, is 5° or more."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting device, surface light source device and display device","description":"This light emitting device includes a light emitting element and a light flux controlling member.
