Abstract
An LCD includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode. The first electrode is provided with a plurality of first elongated electrodes. The second substrate is provided with a second electrode and a third electrode. The second electrode is a common electrode and the third electrode is a pixel electrode. The second electrode is provided with a plurality of second elongated electrodes. The first elongated electrodes and the second elongated electrodes are arranged alternately, and the first elongated electrodes have no overlap with the second elongated electrodes. When no bias voltage is applied between the first electrode and the second electrode, the LCD is displayed with a wide viewing angle; and when a bias voltage is applied between the first electrode and the second electrode, the LCD is displayed with a narrow viewing angle.
