Integrated circuit free from accumulation of duty ratio errors

A liquid-crystal-display device, comprising:

• a liquid-crystal-display panel;
• a gate driver which drives gate-bus lines of said liquid-crystal-display panel;
• and
• a plurality of data drivers which are arranged in cascade connection, and drive data-bus lines of said liquid-crystal-display panel, wherein each of said data drivers receives a signal supplied from a preceding stage and transfers the signal to a following stage after inverting a logic thereof.

The signal-transmission system as claimed in claim 9, wherein each of said integrated circuits includes:

• a first signal-inversion switching circuit which receives the signal supplied from the preceding stage as a first input signal, followed by outputting the first input signal after logic inversion thereof in response to a first state of a switching signal and outputting the first input signal without logic inversion in response to a second state of the switching signal;
• a signal processing circuit which performs signal processing based on the output of said first signal-inversion switching circuit;
• and
• a second signal-inversion switching circuit which receives the output of said first signal-inversion switching circuit as a second input signal, followed by outputting the second input signal after logic inversion thereof to the following stage in response to the second state of the switching signal and outputting the second input signal without logic inversion to the following stage in response to the first state of the switching signal.
