1. A pixel structure, disposed on a substrate, comprising:

  • a patterned semiconductor layer disposed on the substrate;

    a gate insulating layer disposed on the patterned semiconductor layer;

    a first metal layer disposed on the gate insulating layer, wherein the first metal layer has at least one gate line and at least one gate, and the gate is electrically connected to the gate line;

    a first insulating layer disposed on the first metal layer;

    a second metal layer disposed on the first insulating layer, wherein the second metal layer has at least one first data line, at least one source, and at least one first drain, wherein the first data line is electrically connected to the source, and the first drain and the first data line are distanced away from each other for a first distance D1 in a first direction;

    a second insulating layer disposed on the second metal layer, wherein the second insulating layer has at least one patterned opening disposed corresponding to the first drain, and the patterned opening is larger than the first drain;

    a third metal layer, having at least one second drain electrically connected to the first drain, wherein the second drain is disposed corresponding to the patterned opening and on the first drain, the second drain and the first data line are distanced away from each other for a second distance D2 in the first direction, and the second distance D2 is less than the first distance D1;

    a third insulating layer disposed on the third metal layer; and

    a pixel electrode disposed on the third insulating layer, wherein the pixel electrode is electrically connected with the second drain.
