<P>PROBLEM TO BE SOLVED: To provide an optical sheet with which luminance unevenness accompanying temperature rise of a light source can be reduced, and a light source device using the optical sheet, and a display device. <P>SOLUTION: The optical sheet integrated with a lens sheet and a diffusion sheet has a plurality of junction positions for integrating the lens sheet and the diffusion sheet and one of the junction positions is a fixed junction position having substantially no flexibility. The junction positions, other than the fixed junction position, are free junction positions having flexibility in at least one direction, and the optical sheet has the fixed junction position on a straight line in the flexibility direction. <P>COPYRIGHT: (C)2007,JPO&INPIT |
