Abstract
In the case where the gray-scale value of the pixel X is the minimum gray-scale value, the data line driving circuit () outputs a video signal having a voltage obtained by correcting the positive polarity minimum gray-scale voltage corresponding to the minimum gray-scale value only when outputting a positive polarity video signal. In the above, the data line driving circuit () outputs the video signal having the voltage obtained by correcting the positive polarity minimum gray-scale voltage, using a voltage correction amount larger than that which is used in outputting the video signal having the voltage obtained by correcting the positive polarity gray-scale voltage corresponding to the intermediate gray-scale value.
