A liquid crystal display device includes a controlling chip and a circuit wire electrically connected to the controlling chip, both disposed on a printed circuit board, and N wire sets and 2N driving chips, all disposed on a glass substrate. N is a positive integer. A characteristic impedance of the circuit wire is equivalent to an output impedance of the controlling chip. The k-th wire set includes 2k−1 peripheral wires, a midpoint of the first peripheral wire in the first wire set is electrically connected to the circuit wire, characteristic impedances of the peripheral wires in the k-th wire set are 2k times the output impedance, k is an integer, and 1≰k≰N. The driving chips are electrically connected to the N-th wire set, and each of the driving chips adjusts the input impedance according to a control information, so as to make the input impedance 2N times the output impedance. |
