Abstract
A liquid crystal display device is provided. A sub-pixel unit includes a liquid crystal capacitor, a storage circuit, and a switching circuit. The storage circuit is configured to store, in a scanning period of the frame period, a data driving signal provided by a data line and provide the data driving signal to the liquid crystal capacitor in a display period of the frame period. The switching circuit is configured to be turned on in the scanning period to provide a reference voltage to the liquid crystal capacitor.
