Classification: CPC H | IPC H

Claim 2:
3. A light emitting device comprising:
a first layer comprising an organic resin;
a second layer comprising an organic resin;
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; and
a film having elasticity provided over a surface of the first layer which faces away from the transistor,
wherein a channel formation region of the transistor comprises a semiconductor layer,
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 the first conductive layer comprises a region in contact with the semiconductor layer,
wherein a third conductive layer overlaps with the channel formation region of the transistor,
wherein the second conductive layer comprises a region in contact with the first conductive layer and a region in contact with the electrode of the light emitting element, and
wherein the second conductive layer and the third conductive layer comprise a same material.
