Display device

A display device, comprising:

• a first substrate;
• a second substrate;
• a display medium, disposed between the first substrate and the second substrate, a plurality of sub-pixel units being defined on the first substrate and the second substrate, and at least one of the sub-pixel units having at least one first sub-pixel and at least one second sub-pixel;
• a first pixel electrode, disposed on the first substrate and corresponding to the first sub-pixel;
• a second pixel electrode, disposed on the first substrate and corresponding to the second sub-pixel, and the second pixel electrode being separated from the first pixel electrode;
• and
• a transparent electrode, disposed on the second substrate, the transparent electrode corresponding respectively to the first pixel electrode of the first sub-pixel and the second pixel electrode of the second sub-pixel, and the transparent electrode receiving a first common potential and a second common potential, wherein
• when grey levels displayed by the first sub-pixel and the second sub-pixel are in a range of about 96 to 180, and the first sub-pixel and the second sub-pixel respectively have a first flicker value and a second flicker value, a potential difference between the first common potential corresponding to the first flicker value and the second common potential corresponding to the second flicker value is in a range of about −100 mV to 1 V.
