The light source device and liquid crystal display device

The present invention relates to a light source apparatus. When the heat radiating member in case of providing the light source portion, or fixed, it is difficult to achieve miniaturization of the light source apparatus frame, thinned by a screw mounted with the light source substrate. Furthermore there is an increased number of parts problem. Further, when the light source is fixed by an adhesive to a substrate, the reliability is also a problem with the passage of time the adhesive shedding. The light source apparatus and a liquid crystal display device of the present invention, the clamping member (9) integrally formed in the inner surface of the back frame constituting the frame body (1) or front frame (2) of the box light source substrate (6) is attached to the the inner side surface of the lifting body to exert an elastic action. Clamping means (9) The light source substrate (6) is clamped with respect to the housing.
