    Abstract: The present invention proposes a fan-out design, a method of forming the fan-out design and a liquid crystal display adopting the fan-out design. The fan-out design has at least two metallic layers. The metallic layers, serving as conducting wires, are connected to different chip pins for transmitting signals. The two metallic layers are not overlapped near the chip pins and are overlapped away from the chip pins. The two metallic layers are separated from each other with an insulating layer. The two metallic layers are not overlapped near the chip pins, so the thickness of the chip pins is thinner. This can avoid the thickness of the fan-out design from being too thick. Besides, the two metallic layers are overlapped away from the chip pins, so the gap between every two conducting wires is greater. It makes the design and the manufacturing process easier and improves yield rate as well.
