<P>PROBLEM TO BE SOLVED: To provide a light source device capable of raising light reflectivity around a lens and attaining uniformity of luminance, and a display device having the light source device. <P>SOLUTION: The light source device has a light-emitting diode base board 2 wherein light-emitting diodes 1 are mounted on one surface, lenses 4 mounted on one surface of the base board 2 and diffusing light emitted from the light-emitting diodes 1, and reflection sheets 5, 6 having through-holes 51, 61 where the lenses 4 are arranged inside and reflecting the light by facing to one surface of the base board 2. The through-holes 51, 61 of the reflection sheets 5, 6 have large hole sections 51a, 61a and small hole sections 51b, 61b ranging to the large hole sections 51a, 61a, and two reflection sheets are laminated so as to enable to relatively move along the light-emitting diode base board 2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
