PROBLEM TO BE SOLVED: To achieve excellent image display by suppressing the fluctuation in the holding potential of a data line due to the parasitic capacitance of a transistor as an analog switch for sampling of an analog video signal.SOLUTION: In a data driver for an active matrix type liquid crystal display device, a signal obtained by logical inverse operation of a sampling signal from a sampling pulse generation circuit 21 by an inverter 60 is set as a correction signal so as to cancel the fluctuation in the holding potential of each source bus line SLj due to the parasitic capacitance CgdN of an Nch transistor 61 for sampling the analog video signal Video, and the correction signal is given to the source bus line SLj through a capacitance element for compensation 65 having the same capacitance as the parasitic capacitance CgdN. |
