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 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 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. In the case in which a sudden thermal change is caused, therefore, the reflection sheet expands or contracts between the head portion of each of the rivets and the reflection sheet so that the wrinkle can be prevented from being generated over the reflection sheet.

19. A display device, comprising:
-
a substrate on which a light-emitting element for applying light on a display panel is mounted at one surface; a support plate for supporting the other surface of the substrate; a reflection sheet disposed on the one surface of the substrate for reflecting the light applied from the light-emitting element; a substrate hole provided on the substrate; a through hole provided in a corresponding position to the substrate hole in the support plate; an inserting hole provided in a corresponding position to the substrate hole in the reflection sheet; and a rivet having a head portion and a leg portion extended from the head portion and inserting the leg portion from the one surface side of the substrate into the substrate hole, the through hole and the inserting hole; wherein a gap is provided between the head portion and the reflection sheet. - View Dependent Claims (20, 21, 22)

30. A display device, comprising:
-
a substrate on which a light-emitting element for applying light on a display panel is mounted at one surface; a support plate for supporting the other surface of the substrate; a plurality of through holes provided on the substrate and the support plate, of which positions correspond to each other; and a fixture including a head portion and a leg portion protruded from the head portion, inserting the leg portion from the one surface side of the substrate into each of the through holes, and fixing the substrate to the support plate with the head portion disposed on the one surface side of the substrate; wherein a dimension from the substrate to a top of the head portion is set to be smaller than a dimension from the substrate to a top of the light-emitting element. - View Dependent Claims (33, 34, 35, 36)

31. A display device, comprising:
-
a substrate on which a light-emitting element for applying light on a display panel is mounted at one surface; a lens for covering the light-emitting element at the one surface of the substrate; a support plate for supporting the other surface of the substrate, a plurality of through holes provided on the substrate and the support plate, of which positions correspond to each other; and a fixture including a head portion and a leg portion protruded from the head portion, inserting the leg portion from the one surface side of the substrate into each of the through holes, and fixing the substrate to the support plate with the head portion disposed on the one surface side of the substrate, wherein a dimension from the substrate to a top of the head portion is set to be smaller than a dimension from the substrate to a top of the lens. - View Dependent Claims (32)
