Abstract:
A IF inversion driving method writes signal voltage of the same polarity to a signal line over a 1F period, and therefore cannot prevent occurrence of crosstalk caused by coupling. Also, shading is caused. In an active matrix type liquid crystal display device including a pixel array unit 11 formed by two-dimensionally arranging pixels 20 in a form of a matrix, the pixel array unit 11 is divided into a plurality of areas (two areas 11A and 11B in a present example) in a vertical direction, while the plurality of areas being vertically scanned in order (alternately in the present example) in a unit of a row, pixels of the plurality of areas are selected in a unit of a row, and a video signal Vsig reversed in polarity in each H is written to the pixels of the selected row.
