Abstract:
1. A liquid crystal display device, comprising: a plurality of pixels arrayed in a matrix including a plurality of pixel rows and a plurality of pixel columns; a pixel electrode provided for each of the plurality of pixels; a counter electrode facing the pixel electrodes; a liquid crystal layer provided between the pixel electrodes and the counter electrode; a first scanning line, a second scanning line and a third scanning line which are provided for each of the plurality of pixel rows; a first signal line and a second signal line which are provided for each of the plurality of pixel columns; a pixel capacitor including a liquid crystal capacitor and provided for each of the plurality of pixels; a temporary storage capacitor provided for each of the plurality of pixels, the temporary storage capacitor temporarily storing a voltage to be written to the pixel capacitor; first switching elements each of which is to be turned ON/OFF by a scanning signal voltage supplied from the first scanning line and controls electrical connection between the first signal line and the temporary storage capacitor; second switching elements each of which is to be turned ON/OFF by a scanning signal voltage supplied from the second scanning line and controls electrical connection between the temporary storage capacitor and the pixel capacitor; and third switching elements each of which is to be turned ON/OFF by a scanning signal voltage supplied from the third scanning line and controls electrical connection between the second signal line and the pixel capacitor, wherein a capacitance value of the temporary storage capacitor is not less than three times a capacitance value of the liquid crystal capacitor.
