Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A display device comprising a pixel, the pixel comprising:
a first transistor comprising a plurality of channel formation regions;
a second transistor comprising a channel formation region in a semiconductor layer; and
an EL element,
wherein one of a source and a drain of the first transistor is electrically connected to a gate of the second transistor,
wherein the other of the source and the drain of the first transistor is electrically connected to a first wiring,
wherein one of a source and a drain of the second transistor is electrically connected to the EL element,
wherein the other of the source and the drain of the second transistor is electrically connected to a second wiring,
wherein the semiconductor layer is electrically connected to the EL element through a conductive layer,
wherein, in a plane view, each of the first wiring and the second wiring has a region extending in a first direction,
wherein, in the plane view, the second wiring has a first region overlapping with the plurality of channel formation regions of the first transistor, a second region overlapping with the channel formation region of the second transistor, and a third region opposite to the conductive layer,
wherein a width of the third region of the second wiring is larger than a width of the first wiring, and
wherein the width of the third region of the second wiring is smaller than a width of each of the first region and the second region of the second wiring.
