Abstract:
1. A display device in which a plurality of gate wires and a plurality of drain wires which intersect the gate wires are formed on a substrate, pixel regions are defined by the gate wires and the drain wires, and a thin film transistor connected to the gate wire and the drain wire is formed for each of the pixel regions, wherein at least one of the gate wires, the drain wires, a gate leading wire extending from the gate wire and a drain leading wire extending from the drain wire is formed of a light-transmitting patterned conductive film; the light-transmitting patterned conductive film is formed of at least a first light-transmitting patterned conductive film, and a second light-transmitting patterned conductive film laminated on the first light-transmitting patterned conductive film; the second light-transmitting patterned conductive film coats an upper surface of the first light-transmitting patterned conductive film including a step portion forming the upper surface of the first light-transmitting patterned conductive film and a side wall surface of the first light-transmitting patterned conductive film; and wherein the first light-transmitting patterned conductive film and the second light-transmitting patterned conductive film are crystallized.
