"Light Emitting Device And Image Display Apparatus"
Abstract: A light-emitting device includes: a light guiding member; a plurality of light-emitting elements; and a reflection member. A light reflection/exit surface of the light guiding member has a concave-convex pattern including a plurality of convex portions reflecting light emitted from the light-emitting elements inward. On the assumption that L is a distance between the light-emitting elements, t is a thickness of the light guiding member, an incident angle Φ of the light on the light reflection/exit surface is an angle between a line segment obtained by projecting a light path from the light-emitting element to the light reflection/exit surface and a line segment extending from a central point of the light-emitting element to the light reflection/exit surface, and θ is a maximum angle range of reflected light, a value of the angle range .θ decreases as a value of the incident angle Φ increases in a range of 0<Φ
