Abstract
An active-matrix type liquid-crystal display comprising a matrix display panel including a glass substrate, pixel electrodes formed on the substrate, signal lines formed on the substrate, gate lines formed on the substrate, and switching elements formed on the substrate, signal-line drive ICs for applying signal voltages to the signal lines, and gate-line drive ICs for driving the switching elements. The display further comprises power-supply potential control circuits for changing the first and second power-supply potentials (VDD, VSS) of the signal-line drive ICs, each by a predetermined value, in accordance with the signal voltages to be applied to the pixel electrodes.
