Patent number: 8344486Abstract: 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.Type: GrantFiled: July 7, 2009Date of Patent: January 1, 2013Assignee: Sharp Kabushiki KaishaInventors: Tomokatsu Nakagawa, Yasunori Chikawa, Akiteru Rai, Tatsuya Katoh, Takuya Sugiyama
