Patent ID: 8384836

Claim:
A liquid crystal display device having thin film transistors comprising: a transparent substrate; gate electrodes which are stacked above the transparent substrate; source electrodes and drain electrodes which are stacked above the gate electrodes; and semiconductor films each of which is stacked above the gate electrode and controls an electric current between the source electrode and the drain electrode based on an electric field generated by the gate electrode; wherein the semiconductor film is formed into a planar shape, and includes a first region where the semiconductor film overlaps with the gate electrode in plan view and a second region where the semiconductor film does not overlap with the gate electrode in plan view, the source electrode and the drain electrode are not connected to the semiconductor film in the second region, and are connected to the semiconductor film in the first region, a gate insulation film is stacked between the gate electrode and the semiconductor film, the semiconductor film is stacked above the gate insulation film in a contact manner, and the source electrode and the drain electrode are stacked above the gate electrode such that the source electrode and the drain electrode are brought into contact with the gate insulation film and climb over the semiconductor film from one side of the semiconductor film.
