Patent ID: 7982837

Claim:
A liquid crystal display device in which liquid crystal is filled between a first transparent insulating substrate (active substrate) and a second transparent insulating substrate or a color filter, said second transparent insulating substrate or color filter opposing said first transparent insulating substrate, wherein said first transparent insulating substrate has at least one unit pixel having at least one insulating gate-type transistor, a scan line doubling as a gate electrode and a signal line doubling as a source wire of said insulating gate-type transistor, and a pixel electrode connected to a drain wire, on a main surface arranged in a two-dimensional matrix, comprising: a scan line comprising a first metal layer formed on a main surface of the first transparent insulating substrate; a storage capacitor line on a main surface of the first transparent insulating substrate; a plurality of second semiconductor layers, formed on a plurality of semiconductor layer formation regions being on said gate electrode and a plurality of discrete regions, respectively, wherein said pixel electrode has plural branches, and wherein the storage capacitor line and the pixel electrode intersect to form the plurality of discrete regions; and said scan line exposed except at an island-shaped semiconductor layer area in and around the gate electrode, wherein the exposed scan line includes an anode-oxidized layer formed thereon.
