1. A display device comprising an electro-optical medium between two supporting plates, provided with a system of pixels arranged in rows and columns, means for providing row and column connections, during operation, with voltages such that column connections are provided with column voltages during at least a part of a selection period in which rows are selected via drive elements, characterized in that the device is provided with correction means which define the column voltages, dependent on externally applied signals provided during the selection period and externally applied signals during a previous selection period of the same column whereby the correction means correct for a variation of pixel capacitance with voltage in the transmission/voltage characteristic.
