Patent ID: 7755281

Claim:
An electroluminescent device comprising: a substrate; a first light-emitting element group and a second light-emitting element group that is different from the first light-emitting element group, the first and second light-emitting element group each including a plurality of light-emitting elements; and a first barrier layer and a second barrier layer that prevent water from transferring from the substrate; the light-emitting elements including a first electrode, a second electrode, and a light-emitting layer disposed between the first electrode and the second electrode; the first barrier layer and the second barrier layer being disposed in a first layer between the substrate and the light-emitting elements; the first barrier layer being disposed to completely overlap the light-emitting layers of the plurality of light-emitting elements included in the first light-emitting element group, in plan view; the second barrier layer being disposed to completely overlap the light-emitting layers of the plurality of light-emitting elements included in the second light-emitting element group, in plan view; and the first barrier layer and the second barrier layer being separate.
