Abstract: A line structure for fan-out circuit having a dense-line area and a fan-out area is provided. The line structure includes a plurality of dense lines arranged in the dense-line area parallel to a first direction, a plurality of pads disposed in the fan-out area, and a plurality of connecting lines arranged in the fan-out area parallel to a second direction. The connecting lines respectively connect one of the dense lines with one of the pads, wherein at least one of the connecting lines is a wavy line.
