Abstract
An electroluminescence device includes a first, second, and third light emitting elements above a substrate. The first light emitting element includes a first transparent anode, a second transparent conductive film, a third transparent conductive film, a cathode, and a first light emitting function layer including a first luminescent layer which emits a first light of a first color. The second light emitting element includes a second transparent anode, the third transparent conductive film, the cathode, and a second light emitting function layer including a second luminescent layer which emits a second light of a second color, which is different from the first color. The third light emitting element includes a third transparent anode, the cathode, and a third light emitting function layer including a third luminescent layer which emits a third light of a third color, which is different from the first and second colors.
