1. A display device comprising:
a plurality of pixels including a first pixel and a second pixel; and
a common electrode,
wherein each pixel of the plurality of pixels comprises a pixel electrode that includes a horizontal stem, a vertical stem, and a branch;
wherein the branch includes:
a first branch that extends in a first diagonal direction from the horizontal stem and the vertical stem; and
a second branch that extends in a second diagonal direction from the horizontal stem and the vertical stem,
wherein:
a common voltage is applied to the common electrode during one frame period including a first subframe period and a second subframe period,
the first pixel is applied with a first data voltage during the first subframe period and a third data voltage during the second subframe period,
the second pixel is applied with a fourth data voltage during the first subframe period and a second data voltage during the second subframe period,
the first data voltage and the second data voltage are positive voltages higher than a common voltage, and
the third data voltage and the fourth data voltage are negative voltages lower than the common voltage.
