Abstract
In one embodiment of the present invention, each pixel includes first and second subpixels. CS bus lines connected to the respective storage capacitors of the first and second subpixels are electrically independent of each other. A CS voltage has a waveform that inverts its polarity at least once a frame, which includes a first subframe for sequentially scanning a series of odd rows and a second SF for sequentially scanning even rows that have been skipped during the first SF. A source signal voltage varies so as to have two frames or subframes with mutually opposite polarities. A CS voltage has a waveform that has quite opposite consequences on the effective voltage of a subpixel of a pixel connected to the jscan line to be selected during the first subframe and on that of another subpixel of a pixel connected to the (j+1)scan line to be selected during the second subframe. In this manner, the deterioration in display quality, which would be caused if either a source line inversion drive or a block inversion drive is applied to a multi-pixel technology, can be minimized.
