Patent ID: 8101946

Claim:
A light emission device having a first base comprising a transistor and a second base having an optically transmissive substrate and an organic EL element formed at the substrate, the organic EL element comprising a cathode, an anode, and an organic EL layer including a light emission layer positioned between the anode and the cathode, and the first base and the second base being bonded to electrically connect the transistor and the cathode, the light emission device comprising: a first insulating film covering the transistor; a first electrode connected to the transistor via a first through hole formed at the first insulating film; a second insulating film covering the first electrode; a second electrode connected to the first electrode via a second through hole formed at the second insulating film, by connecting the second electrode and the cathode, the cathode and the transistor being electrically connected; and banks positioned at the second base, the light emission layer being positioned between the banks and the cathode being formed so as to cover from the light emission layer to end portions of the banks, wherein a light emitted from the light emission layer of the organic EL element is emitted via the optically transmissive anode and the second base.
