Abstract: There are provided a light source device and a display device which do not generate a wrinkle on an optical sheet even if the optical sheet is held on an LED substrate. A reflection sheet 11 is disposed between each of head portions possessed by a rivet, a positioning rivet and a support rivet and one surface of an LED substrate 8 where an LED is mounted, and a gap in a direction of a sheet thickness is provided between the head portion of each of the rivets and the reflection sheet 11. In the case in which a sudden thermal change is caused, therefore, the reflection sheet 11 expands or contracts between the head portion of each of the rivets and the reflection sheet 11 so that the wrinkle can be prevented from being generated over the reflection sheet 11.

Abstract: Concave marks indicative of an orientation of a circuit board are formed on the circuit board, convex indices to be engaged with the marks are formed in a position in which the circuit is to be attached. An operator confirms the orientation of the circuit board easily and accurately by visually recognizing the marks and touching the marks with a finger. Moreover, the operator positions the circuit board by engaging the marks with the indices.
