Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a planar lighting system using the light with high efficiency and easy to manufacture.SOLUTION: A plurality of angular holes 713 are equally bored with an equal interval in a light incident side (a light source side) end of a light guide plate 71 of a back-light unit 7. An LED 72 formed by mounting COG on a light source FPC 75 is installed in these angular holes 713 while adhering a light emitting surface 721 of the LED to an opposite wall surface 714 through an adhesive resin 77. With this structure, the only transparent adhesive resin layer 77 is interposed between the light emitting surface 721 and the opposite wall surface 714 and an air layer is not interposed, so that the light emitted from each LED 72 efficiently enters the light guide plate 71.
