1. A pixel structure in a liquid crystal display (LCD), comprising:

  • at least one scan line disposed on a substrate and along a first direction in an arrangement;

    at least one connecting electrode disposed on the substrate and along a second direction in an arrangement;

    at least one first data line section and at least one second data line section disposed on the substrate and along the second direction in the arrangement, wherein the first data line section through the connecting electrode electrically connects to the second data line section to form at least one data line, and the data line crosses over the scan line;

    at least one thin-film transistor (TFT) having a gate electrically connected to the scan line, a source electrically connected to the data line, and a drain;

    at least one shielding electrode disposed on the substrate, and the shielding electrode having a main segment being substantially parallel to the data line and along the second direction in the arrangement, wherein the shielding electrode, the source, and the drain are formed by the same metal layer, and the data line is made by at least two metal layers, each having a plurality of metal pattern layers that are electrically connected to each other and not formed simultaneously; and

    a pixel electrode disposed on the substrate, a part of the pixel electrode covering the shielding electrode and electrically connected to the drain;

    wherein the part of the shielding electrode being substantially parallel to the data line is disposed between the pixel electrode and the data line, and at least one dielectric layer disposed between the shielding electrode, the pixel electrode and the data line.
