The present invention relates to a fan-out wiring arrangement of TFT-LCD slim bezel arrangement. The fan-out wiring arrangement includes a first metal layer that is subjected to etching to form parallel first fan-out wires and a second metal layer that is subjected to etching to form parallel second fan-out wires. The first and second metal layers are respectively arranged at upper and lower sides to be parallel to and substantially correspond to each other. The first fan-out wires have line width and fan-out pitch that are identical to those of the second fan-out wires. The first fan-out wires have projections on the second metal layer that are parallel to the second fan-out wires and alternate with the second fan-out wires in an equally spaced manner. The fan-out wiring arrangement realizes wire pitch ≦8 μm, reduces fan-out height, while increasing metal CD, reducing resistance loading, and achieving slim bezel arrangement.
