Classification: CPC H  G | IPC G  H

Claim 1:
2. A display device comprising a pixel, the pixel comprising:
a light-emitting element over a substrate;
a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, and a sixth transistor over the substrate;
a first wiring electrically connected to one of a source and a drain of the first transistor; and
a second wiring electrically connected to one of a source and a drain of the second transistor,
wherein the other of the source and the drain of the first transistor is electrically connected to the other of the source and the drain of the second transistor and one of a source and a drain of the third transistor,
wherein the other of the source and the drain of the third transistor is electrically connected to one of a source and a drain of the fourth transistor and one of a source and a drain of the fifth transistor,
wherein the other of the source and the drain of the fourth transistor is electrically connected to the light-emitting element,
wherein the other of the source and the drain of the fifth transistor is electrically connected to one of a source and a drain of the sixth transistor,
wherein the first wiring is a power supply line and configured to supply current to the light-emitting element,
wherein the first wiring comprises a first region overlapping with a contact hole and a second region having a width narrower than a width of the first region, and
wherein the first region of the first wiring does not overlap with a pixel electrode of the light-emitting element.
