Claim:
An active matrix-type liquid crystal display apparatus comprising: a plurality of data signal lines; a plurality of scanning signal lines intersecting the plurality of data signal lines; a plurality of pixel formation portions arranged in a matrix form so as to correspond to respective intersection points of the plurality of data signal lines and the plurality of scanning signal lines; and a driver circuit for driving the plurality of data signal lines and the plurality of scanning signal lines, wherein the driver circuit includes: a data signal line driver circuit for generating a plurality of data signals representing an image to be displayed, as voltage signals whose polarities are reversed every predetermine number of horizontal periods, and applying the plurality of data signals to the plurality of data signal lines; a precharge circuit for providing, as a precharge voltage, a predetermined positive-polarity or negative-polarity voltage to the plurality of data signal lines during a predetermined precharge period, every one or more predetermined number of horizontal periods; and a scanning signal line driver circuit for selectively driving the plurality of scanning signal lines such that each of the plurality of scanning signal lines is in a selected state during an effective scanning period which is a period other than the precharge period, at least once in each frame period, and the scanning signal line having been in the selected state during the effective scanning period is in a selected state during the precharge period, at least once in a period from a first point in time at which the scanning signal line is changed from the selected state to a non-selected state to a second point in time at which the scanning signal line goes into a selected state during an effective scanning period in a next frame period, each of the plurality of pixel formation portions includes: a switching element that is in an on state when a scanning signal line passing through a corresponding intersection point is in a selected state, and is in an off state when the scanning signal line is in a non-selected state; and a pixel capacitance connected, through the switching element, to a data signal line passing through the corresponding intersection point, and the driver circuit applies the precharge voltage to each data signal line by the precharge circuit and selects each scanning signal line by the scanning signal line driver circuit, such that a polarity of the precharge voltage provided to each data signal line when any one of the scanning signal lines is caused to be in a selected state during the precharge period in each frame period matches a polarity of a data signal applied to said data signal line when said scanning signal line is caused to be in a selected state during the effective scanning period in a next frame period.
