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.

Abstract: In a COF of an embodiment of the present invention, the smaller distance to edges of a heat-releasing member an area of the heat-releasing member has, the larger openings the area has. Accordingly, a volume per area (an area per length) of the heat-releasing member decreases toward the edges. The arrangement improves flexibility of the COF. This prevents a stress caused by bending the COF from concentrating at the edges. This makes it possible to prevent a line on an insulating film from being broken. Also, it becomes possible to prevent an anisotropic conductive resin from coming off which is used to bond the COF with a display panel in providing the COF in a display apparatus.
