Abstract

Disclosed are a light source device and a display device capable of preventing stress from occurring in, for example, connectors and a plurality of circuit boards connected by the connectors when the circuit boards are fixed to a supporting body using fasteners. Specifically disclosed is a light source device which comprises a plurality of circuit boards (2) each having light-emitting elements (1) that are mounted on a first surface (2a) thereof and being disposed so as to be remote from each other such that the surfaces thereof are parallel to each other, a supporting body (6) disposed on second surfaces of the plurality of circuit boards (2) so as to support the circuit boards, and connectors (5) electrically connecting two adjacent circuit boards (2). A plurality of insertion holes (2c, 2d) into which fasteners (8) for fixing the circuit boards (2) to the supporting body (6) are fitted are formed in each circuit board (2) so as to be remote from each other. The size of the insertion hole (2c) among the plurality of insertion holes (2c, 2d) is smaller than that of the insertion hole (2d).

Description

technical field

[0001] The present invention relates to a light source device provided with a light emitting element, and a display device provided with the light source device. Background technique

[0002] A so-called thin liquid crystal display device such as a liquid crystal television includes a substantially rectangular parallelepiped display unit having a display surface on which an image is displayed on the front side, and a light source device arranged on the back side of the display unit to irradiate light to the display unit. Optical sheets such as a diffusion plate and a prism sheet are disposed between the device and the display unit.

[0003] The display unit has a substantially rectangular parallelepiped liquid crystal display panel. Since the liquid crystal display panel itself cannot emit light, it needs an illumination source for displaying video on the display surface, and a backlight device is used as the illumination source.

[0004] The backlight devi...
