Abstract:
An active matrix display device having at least one thin film transistor comprising:a semiconductor layer formed over a substrate having an insulating surface; a first pair of impurity regions formed in said semiconductor layer wherein said first pair of impurity regions include an impurity having one conductivity type at a first concentration; a channel region formed in said semiconductor layer between said pair of impurity regions; a second pair of impurity regions formed between said first pair of impurity regions and said channel region wherein said second pair of impurity regions include said impurity having said conductivity type at a second concentration lower than said first concentration; a gate electrode adjacent to said channel region with a gate insulating film interposed therebetween; an interlayer insulating film formed over said semiconductor layer; an organic resin film formed over said interlayer insulating film, said organic resin film having a leveled upper surface; and a pixel electrode formed over said organic resin film and electrically connected to said semiconductor layer.
