    Abstract: It is to provide a reflection sheet, light source device and display device, not only for uniforming the luminance of light emitted from a light source, but also for utilizing a single sheet material to form the reflection sheet having a frame portion that continues to all rims of a flat portion. The reflection sheet is provided with a flat portion that is formed in a substantially square shape, and a frame portion that is folded at a first fold formed on a rim of the flat portion. It is formed in a case shape. It is provided with three second folds divergent from a corner of the flat portion to a rim of a corner on the frame portion, between each corner of the flat portion and the rim of the corner on the frame portion. No gap and step are generated on the corner.

    Abstract: A light source device includes a circuit board having a light-emitting element mounted on a one surface; a support body positioned on the other surface side of the circuit board for supporting the circuit board; a rivet having a head portion, which is positioned on a side of the one surface of the circuit board and cannot be inserted into a first through hole provided on the circuit board and the support body, and a shaft portion having a tip side stopped and held on the support body in a penetration via the first through hole; and a reflection sheet arranged on the one surface of the circuit board for reflecting light. The light source device provides a second through hole having a diameter larger or smaller than the diameter of the head portion at the position corresponding to the head portion on the reflection sheet.
