Abstract
A liquid crystal display panel includes first and second substrates, first pixel electrodes, second pixel electrodes, common electrodes, first auxiliary electrodes, and a liquid crystal layer. The second substrate is disposed opposite to the first substrate. The liquid crystal layer is disposed between the first and the second substrates. The first pixel electrodes, the second pixel electrodes, and the common electrodes are disposed on the first substrate. The first auxiliary electrodes are disposed on the second substrate. One of the first pixel electrodes is not overlapping one of the first auxiliary electrodes in a vertical projection direction. A driving method of the liquid crystal display panel includes setting a first voltage difference in a wide viewing mode and a second voltage difference in a narrow viewing mode between the first auxiliary electrodes and the common electrodes and, respectively. The first voltage difference is less than the second voltage difference.
