发明名称 Light source device and display device
摘要 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.
