A liquid crystal display includes a plurality of signal lines. The signal lines are parallel to each other in a display area, the distances between the signal lines vary such that the signal lines are arranged like a fan in a fan-out area, and the signal lines are connected to a driving circuit in a connection area. Each signal line includes a single-layered portion and a double-layered portion located in the fan-out area, and the length of the single-layered portion of relatively longer signal line is relatively shorter.
