LIGHT REFLECTING SHEET, LIGHT SOURCE DEVICE, AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light reflecting sheet which expands and contracts by thermal expansion, the light reflecting sheet being configured to be prevented from being positionally displaced in the direction of the surface thereof and in the direction of the circumference thereof to thereby enable the position of the light reflecting sheet to be held at an appropriate position, a light source device, and a display device.

SOLUTION: A light reflecting sheet 7 which is supported by a support body for supporting light sources and reflects the light emitted from the light sources comprises through-holes which penetrate through in the thickness direction and long holes which are separated from the through-holes in the direction along the surface of the sheet and long in the direction of the separation. A light source device is provided with: first shaft bodies fitted in the through-holes to set the position of the light reflection sheet 7 relative to support body; and second shaft bodies fitted in the long holes so as to be movable in the direction of the length of the long holes to set the position of the light reflecting sheet 7 relative to the support body.
