An LCD device includes: multiple data lines, scanning lines, pixel units and switching elements. First terminals of the switching elements are connected together for receiving a control signal. Second terminals of the switching elements are connected together for receiving a reference voltage signal. Third terminal of each switching element is connected to a corresponding data line. When the control signal is a first control signal, each switching element is turned off, grayscale voltage signals are applied on corresponding pixel units, and a normal image frame is displayed. When the control signal is a second control signal, each switching element is turned on, the reference voltage signal is applied on the pixel units, an inserted black frame is displayed. A simple and power-saving way for an inserted black frame is realized to solve the cross talk in 3D display or a serious image smear problem in low refresh rate.
