1. A pixel structure, comprising:
a pixel electrode;
a data line;
a scan line, having a branch and a main body, wherein the branch is connected vertically with the main body, the main body is intersected with the data line, and an extending direction of the main body is intersected with an extending direction of the branch; and
a semiconductor pattern connected between the data line and the pixel electrode and comprising a first region, a second region, a third region, a fourth region, a first channel region, a second channel region, a source-electrode contact and a drain-electrode contact, wherein the source-electrode contact is connected to the data line and the drain-electrode contact is connected to the pixel electrode, the first channel region is connected between the second channel region and the data line and connected between the source-electrode contact and the second channel region, and the second channel region is connected between the first channel region and the pixel electrode and connected between the drain-electrode contact and the first channel region;
wherein the first channel region is a part of the semiconductor pattern overlapping with the main body, the second channel region is a part of the semiconductor patter overlapping with the branch,
wherein none of the first region, the second region, the third region or the fourth region is overlapped with the scan line;
