Abstract:
A liquid crystal display device comprising:a first substrate; a thin film transistor formed over said first substrate, said thin film transistor comprising a semiconductor film having at least a source, a drain and a channel regions, a gate insulating film adjacent to said semiconductor film and a gate electrode adjacent to said channel region with said gate insulating film interposed therebetween; a drain electrode electrically connected to said drain region; a source signal line electrically connected to said source region; a common electrode disposed adjacent to said drain electrode; a second substrate opposed to said first substrate; a liquid crystal interposed between said first and said second substrates wherein an electric field is applied to said liquid crystal substantially in parallel with a surface of said first substrate by said drain electrode and said common electrode, wherein a transparent conductive material is provided over said second substrate.
