ABSTRACT:
The scanning signal line driving circuit sequentially carries out active driving with respect to each set of a certain number of scanning signal lines which are adjacent to each other in a vertical direction, and when carrying out an actual writing with respect to a first set of a certain number of pixel lines adjacent to each other in the vertical direction, carries out pre-charging with respect to a second set of the certain number of pixel lines to which the actual writing is carried out next with a potential of a same polarity as that of the first set of the certain number of pixel lines. In this manner, it is possible to provide a matrix image display device with no irregularities in display quality and is capable of matching the apparent vertical resolution of the device to that of the image source, when using an image signal of vertical resolution lower than the maximum physical vertical resolution of the device.
