Patent ID: 11960174
Assignee: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.
Field: Optics (Instruments)
Classification: CPC G  H | IPC F  G  H

Claim 0:
1. A semiconductor device comprising:
a transistor comprising a first semiconductor film;
a first wiring;
a second wiring functioning as an electrode of a capacitor, the second wiring comprising a metal; and
a third wiring electrically connected to the second wiring,
wherein the transistor, the capacitor, and a display element are included in a pixel,
wherein the first semiconductor film comprises indium, gallium, zinc, and oxygen,
wherein the first wiring and a channel formation region of the transistor overlap each other,
wherein the second wiring and the first semiconductor film overlap each other,
wherein, when seen from above, each of the first wiring and the third wiring has a region extending in a first direction,
wherein, when seen from above, the second wiring has a region extending in a second direction which is different from the first direction,
wherein, in the first direction, a length of a region where the first semiconductor film and the second wiring overlap each other is larger than a length of a region where the first semiconductor film and the first wiring overlap each other, and
wherein, when seen from above, the first semiconductor film has a region overlapping with an electrode of the display element.
