Claim 13:
14. A display device comprising:
a driving transistor including a first electrode, a channel, and a second electrode and disposed on a substrate, the driving transistor including a polycrystalline semiconductor;
a first gate insulating layer disposed on the first electrode, the channel, and the second electrode of the driving transistor;
a gate electrode of the driving transistor disposed on the first gate insulating layer and overlapping the channel of the driving transistor;
a first scan line disposed on the first gate insulating layer;
a second gate insulating layer disposed on the gate electrode of the driving transistor and the first scan line;
a lower second scan line disposed on the second gate insulating layer;
a first interlayer insulating layer disposed on the lower second scan line;
a third transistor including a first electrode, a channel, and a second electrode, the third transistor being disposed in the first interlayer insulating layer and including an oxide semiconductor;
a third gate insulating layer disposed on the first electrode, the channel, and the second electrode of the third transistor;
a gate electrode of the third transistor disposed on the third gate insulating layer;
a second interlayer insulating layer disposed on the gate electrode of the third transistor;
a connection electrode disposed on the second interlayer insulating layer and electrically connecting the gate electrode of the driving transistor and the second electrode of the third transistor; and
a contact portion where the connection electrode electrically contacts the second electrode of the third transistor,
wherein at least a part of the contact portion overlaps the first scan line.
