PROBLEM TO BE SOLVED: To provide a connection board (heat seal) which connects a liquid crystal panel board mechanically and electrically to a circuit board together high in reliability by thermocompression bonding, even if the boards are equipped with terminals of different thickness at each edge of the heat seal. SOLUTION: A display panel-side edge 24 of a heat seal 20 is equipped with a third terminal 26 provided with terminals 28, covered with a resin from outside the third terminal 26, and fixed to a first terminal 46 of a liquid crystal display panel 40 by pressure. A circuit board-side edge 30 of the heat seal 20 is equipped with a fourth terminal 32 provided with terminals, covered with a resin from outside the fourth terminal 32, and fixed to a second terminal 64 of a circuit board 60 by pressure. The display panel-side edge 24 and the circuit board-side edge 30 of the heat seal 20 are set differently in resin thickness from each other, corresponding to a thickness differently between the first terminal 46 of the liquid display panel 40 and the second terminal 64 of the circuit board 60. |
