Abstract
To realize a liquid crystal display device of such a packaging structure that a drive voltage can be supplied to TCPs without being seriously affected by a voltage drop caused by an increased resistance of wires despite a growth in size of a liquid crystal panel, the liquid crystal panel includes: source TCPs connected to source wires; and a circuit substrate for supplying a liquid-crystal-drive signal to the source TCPs. Between the source TCPs, there are provided: transmission panel wires for transmitting the signal supplied by the circuit substrate sequentially from one source TCP to the next; and a flexible substrate for stabilizing the signal transmitted via the transmission panel wires.
