Patent ID: 8829668

Claim:
An electronic device comprising: a first substrate; a pixel portion over the first substrate, and comprising a pixel comprising: a first transistor comprising: a first gate electrically connected to a first gate wiring; a first source; and a first drain, wherein one of the first source and the first drain is electrically connected to a source wiring, and wherein the source wiring crosses the first gate wiring, a second transistor comprising: a second gate; a second source; and a second drain, wherein one of the second source and the second drain is electrically connected to a current supply line, a capacitor comprising: a first electrode electrically connected to one of the second source and the second drain; and a second electrode electrically directly connected to the second gate, a light emitting element electrically connected to the other one of the second source and the second drain; and a third transistor comprising: a third gate electrically directly connected to a second gate wiring; a third source; and a third drain, wherein one of the third source and the third drain is electrically directly connected to the second gate, a second substrate over the pixel portion; a first sealing material interposed between the first substrate and the second substrate, and surrounding the pixel portion; and a second sealing material formed outside of the first sealing material, wherein the second sealing material is in contact with at least a side surface of the second substrate, wherein the first sealing material is in direct contact with the second sealing material, and wherein the first sealing material is not overlapped with the pixel portion.
