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 a pixel including a first transistor, and a driving circuit including a second transistor. The first transistor includes a first active layer including first source and drain regions apart from each other with a first channel region therebetween, a first gate insulating layer on the first active layer and covering the first channel, source and drain regions, and a first gate electrode on the first gate insulating layer and overlapping the first channel region. The second transistor includes a second active layer including second source and drain regions apart from each other with a second channel region therebetween, a second gate insulating layer on a part of the second active layer including the second channel region and exposing the second source and drain regions, and a second gate electrode disposed on the second gate insulating layer and overlapping the second channel region.
