Abstract: Disclosed is a liquid crystal display panel with a switchable viewing angle and a driving method thereof. A pixel unit located in a display area of the liquid crystal display panel comprises: a main pixel region, which is horizontally aligned, wherein pixel electrodes and common electrodes are alternately arranged on the lower substrate and spaced from one another; and a sub-pixel region, which is perpendicularly aligned, wherein upper substrate electrodes and corresponding pixel electrodes are arranged below the upper substrate and on the lower substrate, respectively. When no bias voltage is applied to the upper substrate electrodes in the sub-pixel region, liquid crystal molecules corresponding to the sub-pixel region do not deflect, such that large viewing angle light leakage occurs in the sub-pixel region, thereby achieving narrow viewing angle display. When a bias voltage is applied to the upper substrate electrodes in the sub-pixel region, the liquid crystal molecules corresponding to the sub-pixel region deflect to a flat state, such that large viewing angle light leakage ceases in the sub-pixel region, thereby achieving wide viewing angle display.
