Claim 0:
1. A display device comprising:
a substrate comprising a display area and a peripheral area surrounding the display area;
a plurality of pixel circuit portions and a plurality of signal lines disposed in the display area; and
a driving circuit portion disposed in the peripheral area and connected with the plurality of signal lines,
wherein the driving circuit portion comprises a first transistor including a first active pattern disposed on the substrate, a first gate insulation layer disposed on the first active pattern, a first gate electrode disposed on the first gate insulation layer,
wherein each pixel circuit portion comprises a second transistor including a second active pattern disposed on the substrate, a second gate insulation layer disposed on the second active pattern, and a second gate electrode disposed on the second gate insulation layer,
wherein the first gate insulation layer comprises a first outer portion that does not overlap the first gate electrode in a first direction and is adjacent to a first edge of the first gate electrode but overlaps a first channel region of the first active pattern in the first direction,
wherein the second gate insulation layer comprises a second outer portion that does not overlap the second gate electrode in the first direction and is adjacent to a second edge of the second gate electrode but overlaps a second channel region of the second active pattern in the first direction,
wherein an insulation layer is disposed on the first gate electrode and the second gate electrode,
wherein the insulation layer has a first opening on the first active pattern, and a second opening on the second active pattern,
wherein the first outer portion has a first lateral side spaced apart from the first opening, and the insulating layer fills in a space between the first lateral side and the first opening,
wherein the second outer portion has a second lateral side spaced apart from the second opening, and the insulating layer fills in a space between the second lateral side and the second opening,
wherein a first maximum width of the first outer portion in a second direction different from the first direction measured from the first edge of the first gate electrode to the first lateral side is larger than a second maximum width of the second outer portion in the second direction measured from the second edge of the second gate electrode to the second lateral side.
