Abstract:
A driving method for a liquid crystal display device of the active matrix type, said liquid crystal display device comprising:a pair of substrates and a liquid crystal disposed between the substrates so as to form a matrix of pixels provided with a plurality of pixel electrodes arranged in rows and columns; a plurality of row electrodes and a plurality of column electrodes, respectively, for applying a voltage to the pixels via the pixel electrodes; and a plurality of active elements each provided to a pixel and connected to a pixel electrode, a row electrode and a column electrode, respectively; the driving method comprising driving the liquid crystal display device while inverting a polarity of voltage applied to each pixel every picture scanning field; wherein a picture data of each pixel is corrected based on a voltage to be applied to a column electrode connected to the pixel for a period from a time of selecting an active element at the pixel in a field period to a time of selecting the active element in a subsequent field period; and wherein the picture data of each pixel is corrected based on a voltage value obtained by multiplying a difference in average voltage value between a voltage supplied to the pixel depending on a display picture and a voltage supplied to another pixel, depending on the display picture, provided with an active element connected to a column electrode to which the pixel is also connected, and a correction coefficient &eegr; together.
