Abstract
A scanning signal line drive circuit as a GDM circuit is composed of a plurality of cascade-connected unit circuits and is operated by a multi-phase clock signal in which pulses partially overlap. The nth stage unit circuit includes: an internal node; a diode-connected set transistor connected to a set input terminal; a reset transistor including a drain terminal connected to the internal node, a source terminal connected to a reset state voltage terminal, and a gate terminal connected to the reset input terminal; and an output circuit including an output transistor connected to a clock input terminal and a capacitor, a scanning signal G(n−2), a scanning signal G(n+2), and a scanning signal G(n+1) being supplied to the set input terminal, the reset input terminal, and the reset state voltage terminal, respectively.
