1. A pixel structure, wherein the pixel structure comprises a plurality of scan lines and a plurality of data lines intersecting each other, the scan lines and the data lines define a plurality of sub-pixel sets; wherein each of the sub-pixel sets comprises:
a common electrode;
a first sub-pixel unit, wherein the first sub-pixel unit comprises a first thin film transistor and a first pixel electrode, and a first drain electrode of the first thin film transistor is connected to the first pixel electrode; and
a second sub-pixel unit, wherein the second sub-pixel unit comprises a second thin film transistor and a second pixel electrode, a second drain electrode of the second thin film transistor is connected to the second pixel electrode, a first source electrode of the first thin film transistor and a second source electrode of the second thin film transistor are connected to the same one of the data lines;
wherein the pixel structure further comprises an extension electrode connected to the first drain electrode or the second drain electrode and located between the first pixel electrode and the second pixel electrode;
wherein the first sub-pixel unit is disposed near a corresponding one of the data lines, the second sub-pixel unit is disposed away from a corresponding one of the data lines; and
wherein the extension electrode comprises a first longitudinal electrode section and a second longitudinal electrode section disposed in a longitudinal gap formed between the first sub-pixel unit and the second sub-pixel unit, the first longitudinal electrode section corresponds to the first sub-pixel unit, the second longitudinal electrode section corresponds to the second sub-pixel unit, and the first longitudinal electrode section and the second longitudinal electrode section are disposed separately.
