Zusammenfassung:	A liquid crystal display device having switchable viewing angles includes a display panel and a display control module. The display panel includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The display control module is used for controlling the display panel to display images. The first substrate is provided with a first electrode. The second substrate is provided with a second electrode and a third electrode. The liquid crystal display device further includes a viewing angle control module. The display control module is further used to provide a synchronization signal to the viewing angle control module. According to the synchronization signal, when a next frame following a current frame on which a viewing angle switching signal is received starts to display, the viewing angle control module outputs a periodic alternating voltage for switching viewing angle to the first electrode.
