摘要： A surface light source apparatus including a point light source, a light guide plate which spreads light introduced from the point light source into a planar shape to output the light from a light outgoing plane, and a light blocking member which covers parts of the point light source and the light outgoing plane of the light guide plate. A gap shielding member is projected toward the light outgoing plane from a surface on a side facing the light outgoing plane of the light blocking member. At least a portion facing the light outgoing plane in the gap shielding member is made of a material having a light blocking property.
