ABSTRACT:
In a backlight device, a diffuser plate and a plurality of optical sheets are disposed above a base tray that includes a plurality of cold-cathode tubes therein. The diffuser plate is sandwiched in between a base member, which holds the bottom surface thereof, and a facing portion of an inner frame disposed on the top surface side thereof. A holding protrusion is arranged on the facing portion so as to abut on an exposed portion located on the periphery of the diffuser plate. According to this construction, even when the backlight device is used in an upright orientation, the diffuser plate can be prevented from leaning forward, and thereby pressure applied on the optical sheets can be prevented.
