Abstract:
1. A liquid-crystal display device comprising: a plurality of scan lines arranged in a first direction on a substrate and also functioning as a gate electrode; a storage-capacitor main wiring line arranged between the plurality of scan lines on the substrate in a direction which is parallel to the first direction; a plurality of source wiring lines arranged in a second direction intersecting the first direction; a thin-film transistor including the gate electrode; a picture-element electrode arranged between the plurality of source wiring lines and between the plurality of scan lines; a storage capacitor formed by using the storage-capacitor main wiring line, an insulation layer on the storage-capacitor main wiring line, and an intermediate electrode on the insulation layer; and a drain wiring line connected to a drain electrode of the thin-film transistor and the intermediate electrode; wherein the storage-capacitor main wiring line includes a first transparent electrode and a first metallic wiring line formed on the first transparent electrode, the first metallic wiring line which is smaller in width and has a lower electrical resistance than the first transparent electrode, the drain wiring line includes a second transparent electrode and a second metallic wiring line being smaller in width and having a lower electrical resistance than the second transparent electrode, the intermediate electrode is formed by extending the second transparent electrode, wherein the plurality of scan lines include a third transparent electrode and a third metallic wiring line formed on the third transparent electrode, the third metallic wiring line being smaller in width and having a lower electrical resistance than the third transparent electrode, and an in-pixel storage capacitor is formed by using the scan line, the picture-element electrode, and an insulation layer formed between the scan line and the picture-element electrode.
