Title: Apparatus and method for fabricating substrate of a liquid crystal display device and interconnects therein

Abstract: Connection wires connecting signal wires and element-side terminals on a substrate are formed with a plurality of first parts and second parts as connection parts having predetermined widths. Further, by adjusting thicknesses of the plurality of connection parts of the connection wires, or by forming lamination wires on the first parts as the connection parts so as to attain multi-layer structures, the connection wires are arranged so as to have substantially uniform resistances. This allows a difference between a width of the broadest connection wire and a width of the narrowest connection wire to be suppressed so that the former is approximately twice the latter. Consequently, short-circuiting of a broad connection wire and wire-breaking of a narrow wire can be avoided, while the resistances of the connection wires can be made uniform.
