Abstract

With regard to a display device having an external compensation function, the occurrence of operational failure caused by off-leakage at a transistor is suppressed. A unit circuit configuring a gate driver is provided with a stabilization transistor including a control terminal, a first conduction terminal connected to a first internal node, and a second conduction terminal connected to a first control signal line, a stabilization circuit-configured to control a potential of the control terminal of the stabilization transistor-based on a potential of the first internal node, a first reset transistor including a control terminal, a first conduction terminal connected to a second output terminal, and a second conduction terminal connected to a first reference potential line, and a reset circuit configured to control a potential of the control terminal of the first reset transistor based on the potential of the first internal node.
