Classification: CPC H | IPC H

Claim 1:
2. A light emitting device comprising:
a first layer comprising an organic resin;
a second layer comprising an organic resin; and
a transistor and a light emitting element electrically connected to the transistor, the transistor and the light emitting element being sealed between the first layer and the second layer,
wherein a channel formation region of the transistor comprises a semiconductor layer,
wherein the semiconductor layer has a thickness of greater than or equal to 20 nm and less than or equal to 70 nm,
wherein the semiconductor layer and an electrode of the light emitting element are electrically connected to each other via a first conductive layer and a second conductive layer,
wherein the first conductive layer is configured to function as one of a source electrode and a drain electrode of the transistor,
wherein a third conductive layer overlaps with the channel formation region of the transistor,
wherein the second conductive layer and the third conductive layer comprise a same material, and
wherein at least one of the first layer and the second layer has a thickness of greater than or equal to 3 μm and less than or equal to 15 μm.
