Classification: CPC H | IPC H

Claim 7:
8. 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, and a first gate electrode disposed on the first 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,
wherein the first outer portion comprises a first portion adjacent to a first side edge of the first gate electrode and a second portion adjacent to a second side edge of the first gate electrode that opposes the first side edge, the first portion has a lateral side spaced apart from a first opening, and the second portion has a lateral side spaced apart from a second opening,
wherein the first 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 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,
where a maximum width of the first portion in a second direction different from the first direction measured from the first side edge of the first gate electrode to the first lateral side is different from a maximum width of the second portion in the second direction measured from the second side edge of the first gate electrode to the second lateral side.
