Patent ID: 7728334

Claim:
A display device comprising: a thin film transistor comprising a gate electrode formed over a substrate, an insulating film formed over the gate electrode, a first semiconductor film formed over the insulating film, source and drain regions formed over the first semiconductor film, and a source electrode over the source region, and a drain electrode formed over the drain region; a gate wiring being continuous to the gate electrode, formed between the substrate and the insulating film; a second semiconductor film being continuous to the first semiconductor film, formed over the insulating film; a third semiconductor film being continuous to the source region, formed over the second semiconductor film; a source wiring being continuous to the source electrode, formed over the third semiconductor film; a transparent conductive film formed over the thin film transistor, which comprises a first portion and a second portion; and a pixel electrode comprising the first portion of the transparent conductive film connected to the drain electrode; wherein a portion of the second semiconductor film is wider than the source wiring and the third semiconductor film at least at an intersection of the gate wiring and the source wiring, wherein the second portion of the transparent conductive film overlaps with the source wiring, wherein the transparent conductive film, the source wiring, the second semiconductor film and the third semiconductor film are formed in a source wiring terminal portion, and wherein the transparent conductive film is wider than the source wiring in the source wiring terminal portion.
