Abstract:
A thin film transistor matrix device comprising:an insulating substrate;a plurality of picture element electrodes arranged in a matrix on the insulating substrate;source electrodes connected to the respective picture element electrodes;drain electrodes;active layer connected to the source electrodes and drain electrodes;gate insulating films formed on the active layer, over the source electrodes and the drain electrodes;gate electrodes formed on the gate insulating films, each gate electrode being narrowed with respect to the associated gate insulating film so that side edges of the gate electrode form a step with respect to side edges of the associated gate insulating film, the gate electrodes being formed from a material containing a metal; anda protecting film coating the gate electrodes, the protecting film being one of a resin film, and a polymer film and being not in contact with the source electrodes and the drain electrodes.
