PURPOSE:To provide a stable and high quality joint structure by preventing a joint between a liquid crystal side terminal and a substrate side terminal of a liquid crystal type large display device unit from breaking by a heat cycle in use. CONSTITUTION:A film carrier 32 with bare wires 33 and 34 is inserted between a liquid crystal side terminal 2 and a board terminal and a board of which front and rear sides are reversed to each other. First the liquid crystal side terminal and a film carrier lead are reflow-soldered. Then an intermediate product is reversed, and a lead of the film carrier 32 is aligned with the board side terminal, pressurized, heated, and reflow-soldered. The intermediate product is reversed again, fixed to a frame 11 with adhesive agent and then, using a jig, a film carrier lead near the liquid crystal terminal is bent by 90 deg. and a controlling board is fixed to the frame. |
