Abstract:
1. An active-matrix substrate comprising: a base substrate; a plurality of source lines provided on the base substrate; a plurality of gate lines, which are arranged so as to cross the source lines; a plurality of thin-film transistors, which have been formed on the base substrate and each of which operates in response to a signal that has been supplied to an associated one of the gate lines; and a plurality of pixel electrodes, each of which is electrically connectible to an associated one of the source lines by way of an associated one of the thin-film transistors, wherein each said thin-film transistor is a bottom-gate thin-film transistor, which includes a gate electrode that is electrically connected to an associated one of the gate lines, a gate insulating film that coats the gate electrode, a semiconductor layer that is provided over the gate electrode with the gate insulating film interposed, and source/drain electrodes that have been formed on the semiconductor layer, wherein the source lines are arranged under the gate lines with a first interlayer insulating film interposed and are electrically connected to the respective source electrodes of their associated thin-film transistors through contact holes that have been cut through the first interlayer insulating film; a first conductive member, which has been formed by patterning the same conductive film as the gate lines; and a second conductive member, which has been formed by patterning the same conductive film as the pixel electrodes, and wherein each of the source lines is electrically connected to the source electrodes through the first and second conductive members.
