DRIVING CIRCUIT FOR LIQUID CRYSTAL DISPLAY

摘要

A liquid crystal display having plural liquid crystal cells which are constituted as a matrix, each cell respectively having one transistor and being supplied with image signals by such transistors. The driving circuit for a liquid crystal display of the present invention periodically changes the polarity of the voltage of the image signals and the voltage between both terminals of the liquid crystal cell so as to switch the transistor, and the driving circuit generates gate signals which are impressed on the gate electrode of each transistor, the gate signals having a lowest voltage which is lower than a voltage obtained by subtracting the amplitude voltage of the common electrode of the liquid crystal cells from the lowest voltage in the driving voltage obtained from the image signals.
