Abstract:
1. A method of manufacturing a display device of a type in which a plurality of pixel electrodes are driven by thin film transistors, respectively, the display device including gate wiring lines disposed on a substrate to supply signals to the thin film transistors and a plurality of source wiring lines disposed above the gate wiring lines so as to intersect with the gate wiring lines, the method comprising: forming a gate metal layer on a surface of the substrate; forming a first resist pattern so as to cover a portion of an upper surface of the gate metal layer; etching the gate metal layer using the first resist pattern as a mask to form a first conductive pattern that includes the gate wiring lines; and forming a second resist pattern partially exposing a portion of an edge of an upper surface of the first conductive pattern between the source wiring lines to be formed and covering other portions of the first conductive pattern, and etching the partially exposed portion of the edge of the upper surface of the first conductive pattern through an intermediate point of the first conductive pattern along a direction of thickness.
