    Abstract: A display panel includes a substrate including a component area, a display area at least partially surrounding the component area, and a first non-display area at least partially surrounding the display area. A first wiring is in the display area and extends in a first direction to face the component area. A second wiring is in the display area and extends in the first direction to face the component area. The second wiring is spaced apart from the first wiring with the component area therebetween. A pixel circuit is connected to one of the first and second wirings and includes at least one thin-film transistor. A display element is connected to the pixel circuit. A cross-sectional area of the first wiring crossing in a second direction that is perpendicular to the first direction is different from a cross-sectional area of the second wiring crossing in the second direction.

    Abstract: Provided is a method for fabricating an array substrate. The method for fabricating the array substrate includes forming a semiconductor layer on a substrate, forming a gate electrode which is insulated from the semiconductor layer, forming source and drain electrodes which are insulated from the gate electrode and connected to the semiconductor layer, and forming a pixel electrode connected to the drain electrode. Here, at least one of the forming of the gate electrode, the forming of the source and drain electrodes, and the forming of the pixel electrode includes forming a conductive layer on the substrate, cooling the substrate on which the conductive layer is formed to a temperature of no greater than about 0° C., heating the cooled substrate, and patterning the conductive layer.

    Abstract: A display device includes an active layer in a display area, a first gate insulation layer on the active layer, a first gate line on the first gate insulation layer in the display area, a first signal line in the same layer as the first gate line in a non-display area and including the same material as that of the first gate line including molybdenum, a second gate insulation layer on the first gate line and the first signal line, a second gate line on the second gate insulation layer in the display area, and a second signal line in the same layer as the second gate line in the non-display area and including the same material as that of the second gate line including aluminum or an aluminum alloy. A width of the first signal line is greater than a width of the second signal line.
