<P>PROBLEM TO BE SOLVED: To provide a surface light source device that has a superior performance and a high heat-radiating efficiency, and is inexpensive. <P>SOLUTION: This liquid crystal unit 2 radiates light from the backlight light source 3 to an object, and includes: an LED substrate 32 in which a wiring electrically connected to the backlight light source 3 is formed on one face; a heat-dissipating member 33 that dissipates the heat conducted from the backlight light source 3; the heat-conductive sheet 34 pinched by the wiring of the LED substrate 32 and the heat-dissipating member 33; and a reflecting sheet 35 formed on the face opposite to the contacting face against the heat conducting sheet 34 in the heat-dissipating member 33. The heat dissipating member 33 has a first part installed on the LED substrate 32, and a second part extended to the exterior of the LED substrate 32, wherein the second part is positioned in the side closer to the LED substrate 32 than the face in the first part in which the reflecting sheet 35 is formed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
