1. A display device comprising:

  • two substrates, at least one of which is transparent, liquid crystal material between the substrates, orientation means orienting the molecules of the liquid crystal material substantially parallel to the substrates, electrodes on at least one of the substrates, polarization means, selection means for selecting at least one pixel, an electric field being applied substantially parallel to said substrates in the operating state during selection, and drive means for supplying a signal voltage to an electrode coupled to the pixel, characterized in that the drive means is provided with correction means which, during selection of a pixel, adapt the signal voltage to be supplied to the electrode coupled to the pixel, dependent on an external data voltage supplied during the selection and on the external data voltage supplied during the previous selection of the same pixel.
