Patent ID: 7116302

Claim:
A process of operating an active matrix display device comprising the steps of: supplying an address signal to a gate of a first thin film transistor so that said first thin film transistor is in an ON state; applying a data signal to one of a pair of impurity regions of the first thin film transistor when the first thin film transistor is in the ON state; supplying said data signal to a gate of a second thin film transistor through said first thin film transistor wherein the gate of the second thin film transistor is electrically connected to the other one of said pair of impurity regions of the first thin film transistor; applying a voltage to one of a pair of impurity regions of the second thin film transistor so that said voltage is applied to a pixel electrode, wherein said first thin film transistor is an N-channel type transistor and said second thin film transistor is a P-channel type transistor.
