Abstract:
A liquid crystal display including a liquid crystal panel in which liquid crystals are sandwiched between a pair of substrates, of which on one substrate are formed a plurality of thin film transistors corresponding to pixels and a plurality of interconnection lines for driving the thin film transistors while on the other substrate are formed opposite electrodes; a plurality of TCPs connected to the liquid crystal panel and each having a liquid-crystal driver IC provided therein; and a circuit board for feeding signals to the TCPs; whereinthe circuit board comprises first wirings for feeding a signal which is not electrically connected to the liquid-crystal driver IC;on one side of each of the TCPs are provided a second wiring connected to the liquid-crystal driver IC and connected to a wiring for driving the thin film transistors of the liquid crystal panel, third wirings which are arranged at both sides of the second wiring and connected to the liquid-crystal driver IC and which serve to electrically connect said TCP to its adjacent TCPs on both sides, and a fourth wiring which is formed between the second wiring and the third wirings and which is not electrically connected to the liquid-crystal driver IC;on one side of the liquid crystal panel are provided a group of the wirings for driving the thin film transistors collectively led out in units of corresponding one TCP, and a fifth wiring for electrically connecting TCPs adjacent to both sides of the group of the wirings; and whereinthe first wiring of the circuit board and the fourth wiring of the TCP, the second wiring of the TCP and the group of wirings of the liquid crystal panel, and the third wirings of the TCP and the fifth wiring of the liquid crystal panel are connected to each other, respectively.
