Light emitting apparatus, surface light source apparatus and display apparatus

A light emitting apparatus comprising:

• a light emitting element that is arranged on a substrate and emits light as a point light source comprising a main beam and sub-beams;
• and
• a light flux controlling member that comprises:
• a light control/emission surface that controls a traveling direction of light emitted from the light emitting element;
• a concavity that allows the main beam to enter the light flux controlling member, the main beam being light emitted in a predetermined range of an angle from a reference optical axis serving as a center axis of three-dimensional light fluxes emitted from the light emitting element;
• and
• a back surface that extends in a radial direction from an opening rim part of the concavity and that allows the sub-beams to enter the light flux controlling member, the sub-beams being light other than the main beam emitted from the light emitting element, wherein:
• one of a grid convex part, which arranges a plurality of strips of convex parts in a grid pattern, and a grid concave part, which arranges a plurality of strips of concave parts in a grid pattern, is formed in the back surface of the light flux controlling member and scatters the sub-beams;
• and
• the substrate on which the light emitting element is arranged and the back surface of the light flux controlling member are placed opposite to one another without intervention of a reflective sheet therebetween.
