Patent ID: 8853940

Claim:
A light emitting device comprising: a first substrate; a thin film transistor over the first substrate; an insulating film over the thin film transistor; a first electrode over the insulating film; a bank covering an edge portion of the first electrode; an organic compound layer over the first electrode; a second electrode over the organic compound layer; a second substrate over the second electrode; a seal member for bonding the first substrate and the second substrate; an external input terminal portion; and a first conductive film and a second conductive film, wherein the bank maintains a gap between the first substrate and the second substrate, wherein the seal member overlaps with the insulating film and the seal member does not overlap with the bank, wherein a first region and a second region are under the seal member, wherein the first conductive film is formed in the first region and the second conductive film is formed in the second region, wherein the thin film transistor is electrically connected to the external input terminal portion via the first conductive film, and wherein the first conductive film and the second conductive film are formed from a same layer.
