Method of fabricating an active-matrix liquid crystal display
摘要:
An active-matrix liquid crystal display integrally formed with a driver circuit including: a pair of substrates disposed in opposing relation to each other; and a liquid crystal material sandwiched between the pair of substrates,wherein the pair of substrates includes:a TFT substrate including at least an insulative substrate, source interconnection line and gate interconnection line which are formed in a matrix pattern on the insulative substrate, a thin film transistor provided to each pixel portion for use as a switching element for applying a voltage to a portion of the liquid crystal material which lies at a location where the source interconnection line and the gate interconnection line intersect each other, a pixel electrode connected to a drain electrode of the thin film transistor for supplying a voltage to the liquid crystal material, and a CMOS driver circuit having a CMOS which comprises thin film transistors for supplying an electric signal to the thin film transistor of the pixel portion through the source interconnection line and the gate interconnection line; anda counterpart substrate including an insulative substrate and a counter electrode formed thereon,the thin film transistor provided to the pixel portion being of a first conductivity type and of an offset or LDD structure,at least a first conductivity type thin film transistor of the thin film transistors of the CMOS driver circuit being of an offset or LDD structure.
