Abstract:
1. 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: each of the plurality of pixel formation portions includes: 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.
