In an LCD driven by a data driver 10A of a dot-inversion driving type, the outputs of voltage buffer amplifiers B1 to B12 are connected to respective data-bus lines D1 to D12 of the LC panel. The data-bus lines carry different colour signals; short-circuiting switches S1, S3, S5, S7, S9 and S11 are connected between successive pairs of data-bus lines concerned with the same display colour, and interconnecting lines L1, L2, L4 for the switches are arranged in a staggered configuration on first and second rows. These short-circuiting switches can be formed in a space-saving manner on one side of every other data-bus line, and turned on by a control circuit 13 when the outputs of the voltage buffer amplifier are in a high impedance state, i.e. in a blanking period. <IMAGE> |
