PROBLEM TO BE SOLVED: To reduce disclination in comparison with a conventional dot line inversion driving system while reducing an influence upon gate signal lines or the like to reduce crosstalk. SOLUTION: A liquid crystal display device includes; a data control circuit which supplies gradation voltages to a plurality of data signal lines provided per column of pixel circuit parts comprising a plurality of pixel circuits arranged in a matrix form; a gate control circuit which supplies a driving signal for writing the gradation voltages to pixel circuits, to a plurality of gate signal lines provided per row of pixel circuit parts; and selection circuit which are provided between gate signal lines and respective pixel circuits and control whether the driving signal supplied to gate signal lines should be supplied to the pixel circuits or not. The data control circuit supplies gradation voltage having opposite polarities to adjacent data signal lines, and the gate control circuit not only supplies the driving signal to the gate signal lines but also controls selection circuits to write gradation voltages of the same polarity to pixel circuits in a plurality of adjacent rows.
