A liquid crystal display device is composed of a liquid crystal panel having a matrix array of liquid crystal pixels, a plurality of scanning lines formed along rows of the liquid crystal pixels, and a plurality of signal lines formed along columns of the liquid crystal pixels, and a display control circuit for selecting a row of the liquid crystal pixels via each of the scanning lines and controlling voltages across the liquid crystal pixels of the selected row via the signal lines. The display control circuit includes a signal line driver for sequentially driving the signal lines, and the signal line driver includes a plurality of driver ICs which are connected in cascade by inter-module wirings for transmitting a clock signal and a pixel data signal and each of which sequentially supplies the pixel data signal to a predetermined number of signal lines in synchronism with the clock signal. Particularly, in the liquid crystal display device, each driver IC has a clock waveform shaping circuit for performing a clock signal waveform shaping by regulating a duty ratio of the clock signal to be output together with the pixel data signal to the next driver IC.
