Abstract
An LCD panel includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode thereon. The first electrode is provided with a plurality of stripe-like control electrodes for controlling a viewing angle of the LCD panel. The second substrate is provided with a second electrode and a third electrode thereon. The second electrode is a common electrode for inputting a common voltage to the LCD panel. The third electrode is a pixel electrode formed in each pixel of the LCD panel. When no bias voltage is applied to the stripe-like control electrodes of the first electrode, the LCD panel is displayed with a wide viewing angle; and when a bias voltage is applied to the stripe-like control electrodes of the first electrode, the LCD panel is displayed with a narrow viewing angle.
