Abstract:
1. A method of manufacturing a display substrate, the method comprising: forming a gate electrode of a switching element in a display area of a base substrate and a first conductive line of a fan-out line in a peripheral area of the base substrate, using a first conductive layer; forming a gate insulating layer including a first contact hole through which the first conductive line is exposed; forming source and drain electrodes of the switching element in the display area and on the base substrate, and a second conductive line of the fan-out line which contacts the first conductive line through the first contact hole in the peripheral area and overlapping with the first conductive line, using a second conductive layer; forming a protecting layer including a second contact hole through which the drain electrode is exposed; and forming a pixel electrode which contacts the drain electrode through the second contact hole, wherein the first and second conductive lines of the fan-out line connect a signal line in the display area with a pad in the peripheral area, and are each elongated to the pad to define a multi-layered structure of the fan-out line and the pad in which the first conductive line overlaps with the second conductive line.
