Abstract
A display device includes a dynamic ratio less shift register which is operated in a stable manner and can expand the degree of freedom of design. In the dynamic ratio less shift register which is provided with thin film transistors having semiconductor layers made of p-Si on a substrate surface, a node which becomes the floating state is connected to a fixed potential through a capacitance element.
