Abstract:
A liquid crystal display comprising: a picture element electrode connected to a gate line and to a source line provided orthogonal to said gate line through a switching device; a display panel arranged facing to said picture element electrode and in which a picture element having a common electrode holding a liquid crystal between the picture element electrode and the common electrode is provided to form a matrix; a drive circuit for applying a gate potential having a first voltage for selecting the gate line and a second voltage for not selecting the gate line (first voltage>second voltage) to the gate line of said display panel; and a common electrode generation circuit for applying a common potential inverting to a high potential or a low potential for each scanning period to the common electrode of the display panel; wherein the second voltage changes synchronously with the common potential, and with respect to a potential difference between the second voltage and the common potential, the potential difference at the high potential of the common potential is smaller than that at the low potential of the common potential.
