Abstract:
1. A liquid crystal display device, comprising: a plurality of pixels arranged in a matrix pattern of a plurality of rows and a plurality of columns, each pixel including a first sub-pixel and a second sub-pixel capable of exhibiting different brightnesses at least at a certain gray level; a plurality of source bus lines each associated with pixels along one of the plurality of columns; a plurality of gate bus lines each associated with pixels along one of the plurality of rows; a plurality of TFTs each associated with at least one of the first sub-pixel and the second sub-pixel of one of the plurality of pixels; and a plurality of storage capacitor bus lines each associated at least with one of the first sub-pixel and the second sub-pixel of each pixel along one of the plurality of rows, wherein each of the first sub-pixel and the second sub-pixel includes a liquid crystal capacitor and a storage capacitor, a storage capacitor bus line associated with the storage capacitor of the first sub-pixel of one of the plurality of pixels is electrically independent of a storage capacitor bus line associated with the storage capacitor of the second sub-pixel of the pixel; a source driver configured to supply source signals to the source bus lines so that when polarities of source signal voltages applied to the plurality of source bus lines do not change over a plurality of horizontal scanning periods, an image write pulse of a gate signal supplied to a gate bus line that corresponds to pixels along a j the source driver configured to supply the source signals to the source bus lines so that after the source signal voltages change to values that correspond to pixels along the j a control circuit configured to supply storage capacitor signal voltages to the storage capacitor bus lines so that polarities of the storage capacitor signal voltages applied to storage capacitor bus lines that correspond to sub-pixels of pixels along the j
