Patent ID: 11901485
Assignee: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A display device comprising:
a first pixel including a first transistor, a second transistor and a first light-emitting element; and
a second pixel next to the first pixel,
wherein the first light-emitting element includes a first electrode electrically connected to the second transistor,
wherein the first transistor includes a first oxide semiconductor layer in a channel formation region,
wherein the first oxide semiconductor layer includes a region overlapping a first wiring,
wherein a portion of the first wiring is configured to be a gate electrode of the first transistor,
wherein, in a plan view, a channel length direction of the first transistor crosses a direction in which the first wiring extends,
wherein, in the plan view, the channel length direction of the first transistor is aligned with a channel length direction of the second transistor,
wherein, in the plan view, the first oxide semiconductor layer does not have a region overlapping a light-emitting region of the first pixel, and
wherein, in the plan view, the first oxide semiconductor layer has a region overlapping a light-emitting region of the second pixel.
