Abstract
In liquid crystal display system 10 which has a matrix arrangement of scanning electrode group 12 and data electrode group 13 and in which each electrode group is driven by a pulse like waveform, this is a liquid crystal display system in which a lower level region than the pulse wave peak value is formed in at least one of the rising or the falling portions of the pulse wave which drives at least one of the electrode groups. A liquid crystal display system with a uniform display with extremely little display non-uniformity can be obtained.
