Abstract
A liquid crystal display apparatus has a liquid crystal display device including a first substrate having scanning electrodes, a second substrate having information electrodes, the scanning electrodes and the information electrodes forming a matrix electrode structure, and a liquid crystal interposed between the first and second substrates, a clock generator circuit for generating clock pulses, scanning electrode drivers for forming a scanning signal and applying the scanning signal to one of the scanning electrodes each time a clock pulse is supplied from the clock generator circuit, and information electrode drivers for forming an information signal and applying the information signal to the information electrodes each time a clock pulse is supplied from the clock generator circuit. The width .delta.t0 of at least one of a plurality of clock pulses SCLK supplied from the clock generator circuit in one horizontal scanning period T is different from the width .delta.t1 of the other clock pulses.
