    摘要： A display device includes a first transistor including a gate electrode, a second transistor including a lower gate electrode, an upper gate electrode, and a first end portion electrically connected to an end portion of the first transistor, a lower gate signal line extending in a first direction, an upper gate signal line disposed on the lower gate signal line and extending in a first direction, and a first connection pattern disposed on the upper gate signal line, electrically connecting the gate electrode and a second end portion of the second transistor, and intersecting the lower gate signal line and the upper gate signal line. An entirety of the upper gate signal line overlaps a part of the lower gate signal line in an overlapping area in which the lower gate signal line or the upper gate signal line overlaps the first connection pattern.

    摘要： A display device includes pixels. Each of the pixels includes: a first transistor including a gate electrode connected to a first node, a first electrode connected to a second node, and a second electrode connected to a third node; a second transistor including a gate electrode connected to a first scan line, a first electrode connected to a data line, and a second electrode connected to the second node; a first sub-transistor including a gate electrode connected to the first scan line, a first electrode connected to the first node, and a second electrode connected to a fourth node; and a second sub-transistor including a gate electrode connected to the first scan line, a first electrode connected to the fourth node, and a second electrode connected to the third node. A channel width of the second sub-transistor is wider than a channel width of the first sub-transistor.
