Abstract:
A active matrix display device comprising:a substrate having an insulating surface; a signal line formed over a substrate; a first thin film transistor having a first channel region and a first pair of impurity regions formed in a first semiconductor film over said substrate wherein a first gate electrode of said first thin film transistor is connected to said signal line; a voltage supply line formed over said substrate; a second thin film transistor having a second channel region and a second pair of impurity regions formed in a second semiconductor film over said substrate; and a pixel electrode formed over said substrate wherein said pixel electrode is connected to said voltage supply line through at least said second thin film transistor, wherein at least one of said first and second thin film transistors has at least one LDD region between the channel region and at least one of the impurity regions.
