PURPOSE: To provide such a driving circuit which enables the observation of correct gradation displays over the entire surface of the panel.
CONSTITUTION: This driving circuit for the active matrix type liquid crystal panel has a scanning bus driver 1 for impressing scanning signals successively to the scanning bus line of the liquid crystal panel 10, a data bus driver 2 for applying the gradation voltages corresponding to digital input data expressing multiple gradations to the data bus line of the liquid crystal panel 10 and a control means 3 for supplying control signals. The differences between the common voltage to be applied to the common electrode of the liquid crystal panel 10 and the gradation voltages are applied to the respective liquid crystal cells. The above-mentioned driving circuit is so constituted as to have an applied voltage correcting means 4 for changing the voltages to be applied to the liquid crystal cells according to the positions of the scanning bus line.
