Abstract
An electro-optic device includes a shift register and another circuit. Source and drain regions of transistors in the shift register contain the same kind of impurity as that contained in the source and drain regions of transistors in the other circuit and contain a higher concentration of the impurity than a concentration of the impurity in the source and drain regions of transistors in the other circuit.
