Abstract: A high-reliability COG-type liquid crystal display device is produced with a high production yield without using a thermo-compression bonding process thereby preventing the connection of a liquid crystal driver IC from encountering a failure which would otherwise occur due to a high temperature in the thermo-compression bonding process. The liquid crystal display device comprises a pair of substrates (13, 14) facing each other via a liquid crystal, at least a liquid crystal driver IC (7) mounted on one substrate (13) by means of direct connection to the one substrate (13), and a plurality of semiconductor input terminals (21) formed on the substrate (13) so that signals are applied to the IC (7) via the semiconductor input terminals (21). The semiconductor input terminals (21) of the liquid crystal panel (8) are connected to semiconductor driving output terminals (6) of a portable telephone device or the like via an elastic connector (12).
