Abstract: A thin-film transistor of the reversed stagger type is provided with a gate electrode, first and second gate insulating films, a semiconductor layer, separated contact layers, and source electrodes and drain electrodes, all of which are stacked on a substrate. Upon manufacturing the thin-film transistor of this type, a gap section is pattered in a single contact-material layer. In this case, the contact-material layer is patterned by carrying out etching by the use of the source electrode and drain electrode as direct masks or by the use of a resist pattern that was used for forming the respective electrodes. Upon patterning a gap section in the contact-material layer between the source electrode and the drain electrode, no dedicated resist pattern is required; therefore, it is possible to reduce the number of the processes as compared with conventional manufacturing methods.

Abstract: A liquid crystal display device incorporating an active matrix substrate having an inter-layer insulating film between a pixel electrode and gate and source signal lines. In this liquid crystal display device, the source signal line has a double-layer structure of an upper-layer line and a lower-layer line, but the upper-layer line is eliminated at the intersection of the gate signal line and the source signal line. This structure prevents a decrease in the thickness of the inter-layer insulating layer on the intersection of the gate signal line and the source signal line.
