Abstract
A display device includes a substrate, a first active pattern, a first gate electrode, a second active pattern, a second gate electrode, a first connecting pattern, and a second connecting pattern. The first connecting pattern is disposed on the second active pattern and is electrically connected to the first gate electrode, and the second connecting pattern is disposed on the first connecting pattern and is electrically connected to the first connecting pattern and the second active pattern.
Claims20
A display device, comprising:
- a substrate;
- a first transistor disposed above the substrate and including:
- a first active pattern covered by a first gate insulating layer;
- and
- a first gate electrode covered by a first interlayer insulating layer disposed between the first gate insulating layer and the first interlayer insulating layer, wherein the first transistor generates a driving current;
- a second transistor disposed above the first gate electrode and including:
- a second active pattern covered by a second gate insulating layer;
- and
- a second gate electrode covered by a second interlayer insulating layer disposed between the second gate insulating layer and the second interlayer insulating layer, wherein a first end of the second active pattern is electrically connected to a first end of the first active pattern, and a second end of the second active pattern is electrically connected to the first gate electrode of the first transistor;
- a first connecting pattern disposed above the second active pattern and connected to the first gate electrode;
- and
- a second connecting pattern disposed above the first connecting pattern and connected to the first connecting pattern and the second end of the second active pattern.
