Abstract:
A liquid crystal panel comprisinga driving substrate; an insulating film formed on said driving substrate; a semiconductor thin film formed above said insulating film as an active layer of a thin film transistor and defining a source region, a drain region, and a channel part under a gate electrode formed on said thin film, said source region and said drain region provided on both sides of the channel part; a plurality of said thin film transistors each respectively driving each of an associated plurality of pixel electrodes; and a light-shielding layer formed in said insulating film between said thin film of said thin film transistor and said driving substrate, wherein said light-shielding layer comprises a material having a resistance of 10 k&OHgr; per square or more shielding a region extended at least a distance from edge parts of the source region and the drain region in the longitudinal direction of said channel region; and a plurality of electrodes connected to the source and the drain regions on an insulating film covering said thin film transistor, wherein said light-shielding layer shields at least edge parts of at least one of said source and said drain regions, and wherein a low concentration region is formed in said edge parts of said source/drain shielded by said light-shielding layer.
