PURPOSE:To increase the freedom of layout for a TCP element and to improve reliability in an electrical connection part by connecting the other edge of the lead wire of the TCP element and a circuit substrate with a pin lead which can be subjected to plastic machining and deformation easily. CONSTITUTION:The other edge of a lead wire 5 where one edge is connected to the input side of a TCT system element 4 and a circuit substrate 7 are connected by a pin lead 8 which can be subjected to plastic machining easily, is highly flexible, and is made of metal and then can be deformed in the longitudinal direction easily by providing a curved part 9 halfway, thus preventing stress due to bending operation from being applied to the lead wire part 5 consisting of a metal foil pattern of the TCP 4 with a relatively long strength. Also, bending operation is performed to the metal wire pin lead 8 which is relatively strong, thus preventing the reliability in the conduction function from being reduced. Further, a specific number of leads are formed in one piece to achieve a lead frame type manufacture. |
