Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light guide member which is laminated on an upper surface of a light-emitting element mounted base plate which is mounted with an LED and the like, and in which a luminance of a part right above the light emitting element is lowered and a luminance distribution on a light emitting face of the light guide member can be uniform, and which has an high light utilization ration to get a high luminance, and moreover, which can make a thinner and smaller plane light source device provided with this light guide member, and provide a plane light source device and a display device using this plane light source device. SOLUTION: The light guide member is laminated on an upper surface of a light-emitting element mounted base plate which is mounted with a light-emitting element and is to disperse and guide light from the light-emitting element, and is provided with a light reflecting part in an area other than a neighboring area of the light-emitting element on the rear face of the light guide member.
