Claim 0:
1. A display device comprising:
a substrate including a display region and a non-display region;
a plurality of pixels in the display region, the plurality of pixels each including at least one transistor, a storage capacitor connected to the at least one transistor, and a light emitting element connected to the at least one transistor;
a plurality of scan lines connected to each of the plurality of pixels, the plurality of scan lines extending in a first direction;
a data line connected to each of the plurality of pixels, the data line extending in a second direction crossing the first direction; and
a power line supplying a first power voltage to the light emitting element,
wherein the at least one transistor includes:
an active pattern provided on the substrate;
source and drain electrodes each connected to the active pattern;
a gate electrode provided on the active pattern with a gate insulating layer interposed therebetween to overlap the active pattern;
an insulating interlayer covering the gate electrode and including a first insulating interlayer;
a second insulating interlayer, and a third insulating interlayer, which are sequentially stacked; and
a protective layer provided on the insulating interlayer, and wherein the power line includes:
a first conductive pattern mainly extending in the first direction, the first conductive pattern being provided on the first insulating interlayer;
a second conductive pattern mainly extending in the first direction, the second conductive pattern being provided on the second insulating interlayer, the second conductive pattern being connected to the first conductive pattern through a first contact hole; and
a third conductive pattern mainly extending in the second direction, the third conductive pattern being provided on the third insulating interlayer, the third conductive pattern being connected to the second conductive pattern through a second contact hole.
