Abstract
An LCD with switchable viewing angle includes a first substrate, second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode and a second electrode. In an embodiment, the first electrode is a pixel electrode, and the second electrode is a common electrode. The second substrate is provided with a third electrode. Liquid crystal molecules in the liquid crystal layer are positive liquid crystal molecules. When a first bias voltage is applied to the third electrode, the LCD is displayed with a wide viewing angle; and when a second bias voltage greater than the first bias voltage is applied to the third electrode, the LCD is displayed with a narrow viewing angle.
