Patent ID: 7394095

Claim:
An thin film transistor substrate comprising: signal wirings, scanning wirings at right angles to the signal wirings, a thin film transistor comprising: a substrate, gate electrodes on the substrate, an insulating film having on the surface thereof a liquid-repellent region and a liquid-attracting region on the gate electrodes, source electrodes and drain electrodes on the liquid-attracting region, and protective film on the source electrodes, the drain electrodes and the liquid-repellent region, at or close to an intersection of the signal wirings and scanning wirings, the drain electrodes having a self-aligned shape in which a pattern shape of the gate electrodes is generally reversed, which further comprises: signal terminals at a terminal of the drain electrodes, and an electrode pattern for the signal terminals placed in a same plane as the gate electrodes so as to surround the signal terminals.
