发明名称 LIQUID CRYSTAL DISPLAY
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 betaH, TP/4<=beta<3.TP/4 is satisfied. Consequently, even if a still picture is presented, the difference in luminance between the subpixels is hardly sensible as unevenness, thus achieving good display quality.
