FIG. 1B is a cross-sectional view. A connector 3 and a panel contactor connecting part 8 join a portion for connecting the output of the driver IC 11 to the contactor 5 of the liquid crystal panel, which receives the output of the driver IC 11 by the connecting substrate 1 and the cable 2. The connector 3 to the contact 5 with the liquid crystal panel is connected to the contact 5 with the liquid crystal panel via the connector terminal 4 of the connector 3 and the jumper wire 13a. The reinforcement component 10 is an accessory component for strengthening the connection between the reinforcement substrate 7 and the connection component 8.
