A liquid crystal display device (LCD) comprises sets of row address conductors (10) and column address conductors (11) which are coupled to liquid crystal pixels (12) arranged in a matrix of rows and columns for displaying images. A drive circuit (20-24) for such a display panel generates selection voltages (Vr) to be supplied to one of the sets of address conductors (10, 11), and data voltages (Vk) to be supplied to the other set of address conductors (10, 11), which data voltages (Vk) are related to a received display information signal (VI). To reduce a mutual influence of the pixels connected to the selection address conductor, which influence is caused by charge currents flowing via a common impedance arranged in series with said selection address conductor, the drive circuit (20-24) further comprises an averaging circuit (23) for generating a correction signal (C) and for averaging an information signal (Im) related to the display information signal (VI) over an averaging period which is related to a line period of the information signal (Im). The drive circuit (20-24) is further provided with a voltage correction circuit (22) for generating at least a power supply voltage (CV) corrected in dependence upon a correction signal (C) to be supplied to at least one of the sets of address conductors (10, 11).
