A display apparatus includes a display panel and a switching panel disposed outside the display panel. The switching panel includes a first base, first and second electrodes disposed on the first base, a second base, third and fourth electrodes disposed on the second base, and a liquid crystal layer disposed between the first base and the second base. When the display apparatus is operated in a first anti-peep mode, the first electrode and the second electrode disposed on the first base have a first AC driving signal and a second AC driving signal respectively, and the third electrode and the fourth electrode disposed on the second base have DC reference signals respectively, wherein the first AC driving signal and the second AC driving signal are in synchronization.
