Abstract:
A display device may include a first pixel coupled to an emission control line, and an emission control stage for selectively coupling the emission control line to a first or second supply voltage line. The emission control stage may include: a first emission control transistor including a first electrode coupled to the first supply voltage line, a second electrode coupled to the emission control line, and a main gate electrode coupled to a first node; a second emission control transistor including a first electrode coupled to the emission control line, a second electrode coupled to the second supply voltage line, and a main gate electrode coupled to a second node; and a third emission control transistor including a first electrode coupled to the first supply voltage line, a second electrode coupled to the first node, a main gate electrode coupled to the second node, and a sub-gate electrode.
