Abstract: Accommodating spots (13) for accommodating circuit elements (25) are formed for the respective circuit elements (25) in an opposing surface (11U), which is one surface of a backlight frame (11) opposed to a circuit element mounting surface (23B) on which the circuit elements (25) are mounted.

Abstract: Disclosed is a reinforcement frame (38) fixed to an outer package (37) of a heated component unit in a display (69), wherein a first heat dissipation fin is included in the reinforcement frame (38). With such an arrangement, even when heat generated when a component unit (such as a backlight unit in a liquid crystal display) is driven, e.g. driving heat of various elements included in the component unit, is transmitted to the outer package (37) of the component unit, the driving heat is further transmitted to the reinforcement frame (38) which is in contact with the outer package (37) and dissipated by means of the first heat dissipation fin. Consequently, the various elements in the component unit are not impaired by driving heat.
