1. A display panel comprising:
a first substrate comprising a pixel display region, the pixel display region comprising pixel units arranged in an array, and pixel electrodes being disposed in the pixel units; and,
a second substrate disposed opposite to the first substrate, a common electrode being disposed on a side of the second substrate facing the first substrate, wherein the common electrode comprises a first common electrode, a second common electrode, a plurality of main electrodes, and a plurality of secondary electrodes, the plurality of main electrodes and the plurality of secondary electrodes are disposed between the first common electrode and the second common electrode, and the plurality of main electrodes and the plurality of secondary electrodes face the pixel electrodes in the pixel units,
wherein each of the plurality of main electrodes surrounds and is spaced apart from each of the plurality of secondary electrodes; each of the plurality of main electrodes is electrically connected to the first common electrode to receives a first voltage signal, each of the plurality of secondary electrode is electrically connected to the second common electrode to receives a second voltage signal, and the first voltage signal is different from the second voltage signal, so that a deflection direction of liquid crystals located in a main electrode region is different from a deflection direction of liquid crystals located in a secondary electrode region.
