DISPLAY DEVICE AND METHOD OF PROVIDING THE SAME

A display device includes a first transistor including a first active pattern including a first oxide semiconductor, and a first gate electrode which is on the first active pattern, a second transistor including a second active pattern including a second oxide semiconductor different from the first oxide semiconductor, and a second gate electrode which is on the second active pattern, a first gate insulating pattern between the second active pattern and the second gate electrode, a second gate insulating pattern facing the first gate insulating pattern with the second active pattern therebetween, and a third gate insulating pattern between the first active pattern and the first gate electrode, the third gate insulating pattern directly contacting the first active pattern and the first gate electrode.
