Patent ID: 7244962

Claim:
An electronic apparatus having at least one display device, said display device comprising: a substrate having an insulating surface; a plurality of pixels in a matrix over said substrate; at least one n-channel type thin film transistor provided at each of said pixels, said n-channel type thin film transistor comprising: a semiconductor film having a pair of impurity regions and a channel region interposed therebetween, and a pair of lightly doped regions between said channel region and said pair of impurity regions; a gate insulating film formed on said semiconductor film; a gate electrode formed over said channel region with a gate insulating film interposed therebetween, said gate electrode comprising a first conductive layer formed on said gate insulating film, and a second conductive layer formed on said first conductive film, wherein said second conductive layer extends beyond side edges of said first conductive layer to contact with said gate insulating film, and an extended portion of said second conductive layer overlaps said pair of lightly doped regions partly.
