Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a surface light source device for improving brightness and uniformity thereof, a display device having this surface light source device and a liquid crystal display device having this display device. SOLUTION: The surface light source device includes a main body; a voltage applying unit; a conductor; and an invisible light beam generation member. The main body includes a plurality of light-emitting spaces. The unit is disposed on an outside face of the main body to respectively generate invisible light beams in each of the space. The conductor is disposed on an inside face of the main body opposite the unit. The member is disposed on the inside face of the main body to alter the invisible light beams to visible light beams. Accordingly, the brightness and the uniformity of the brightness of the source device is improved, and a drive voltage and a consumption power quantity is reduced. COPYRIGHT: (C)2005,JPO&NCIPI
