摘要： 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 jth scan line to be selected during the first subframe and on that of another subpixel of a pixel connected to the (j+1)th 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.

摘要： Each pixel includes first and second subpixels and two switching elements provided for those subpixels. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the first and second subpixels are electrically independent. A storage capacitor counter voltage applied to each storage capacitor counter electrode by way of its associated storage capacitor line has a first period (A) with a first waveform during one vertical scanning period. The first waveform oscillates between multiple voltage levels in a first cycle time (PA) that is an integral number of times (and at least four times) as long as one horizontal scanning period (H). Each of the voltage levels has a flat portion with a duration TP. While the two switching elements are ON, a display signal voltage is applied to the respective subpixel electrodes and respective storage capacitor electrodes of the first and second subpixels. After the two switching elements have been turned OFF, voltages at the storage capacitor counter electrodes of the first and second subpixels change. And if an interval between a point in time when the two switching elements in ON state have just been turned OFF and a point in time when the storage capacitor counter voltage changes for the first time is βH, TP/4≦β

摘要： A color display pixel PCD in a liquid crystal display device (100) includes first through fourth pixels P1 through P4 arrayed in two rows by two columns, and first and second signal lines (13a, 13b) which are located in correspondence with each column of pixels and are supplied with signal voltages of polarities opposite to each other from a signal line driving circuit (30) in each vertical scanning period. A TFT (14) of one of the first and third pixel P1 and P3 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). A TFT (14) of one of the second and fourth pixel P2 and P4 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). The TFTs (14) of the first through fourth pixels P1 through P4 are controlled to be ON/OFF by a common scanning signal, and the polarities of the signal voltages supplied to the first and second signal lines (13a, 13b) are constant during an arbitrary vertical scanning period. Owing to this, the load on the signal line driving circuit is reduced.
