Abstract

In the thin-film transistor device: the stacked thickness of either a source electrode or a drain electrode and a corresponding one of silicon layers is the same value or a value close to the same value as the stacked thickness of a first channel layer and a second channel layer; the stacked thickness of the first channel layer and the second channel layer is the same in a region between the source electrode and the drain electrode and above the source electrode and the drain electrode; the first channel layer and the second channel layer are sunken in the region between the source electrode and the drain electrode, following a shape between the source electrode and the drain electrode; and the gate electrode has one region overlapping with the source electrode and an other region overlapping with the drain electrode.
