    摘要： A gate line driver is provided and includes first to second transistors and first to third switches. The first transistor and the second transistor are coupled in series between a first voltage terminal and a second voltage terminal. The first switch has a first terminal coupled to a first node between the first and second transistors. The second switch has a first terminal coupled to a third voltage terminal and a second terminal coupled to a second terminal of the first switch at a second node. The third switch has a first terminal coupled to the third voltage terminal, a second terminal coupled to the first node, and a third terminal coupled to the second node.

    摘要： A display device includes a current-driven electro-optical element, a first supply, a second supply, a driving transistor, a correction transistor, an anode switching transistor, an initialization transistor, and a capacitive element. A current is supplied from the first supply. The second supply is lower in potential than the first supply. The driving transistor is configured to drive the electro-optical element in accordance with a written image signal. The correction transistor is coupled between a gate of the driving transistor and a second terminal of the driving transistor. The anode switching transistor is coupled between the second terminal of the driving transistor and an anode of the electro-optical element. The initialization transistor is coupled between the anode of the electro-optical element and the second supply. The capacitive element is coupled to the gate of the driving transistor. The correction, anode switching, and initialization transistors are n-channel transistors.
