Abstract
In a display device driven with an active matrix the capacitances associated with the pixels (2) are first discharged or charged as far as or beyond the range of transition in the transmission/voltage characteristic before they are accurately adjusted. A capacitive element (10) is connected in parallel with a series arrangement of first (5) and second (8) asymmetrical non-linear switching elements and stores an electric charge which is used for discharging or charging the pixels.
