Patent ID: 8648528

Claim:
An electroluminescent device comprising: a substrate that has a first edge and a second edge opposed to the first edge; a wiring substrate that is disposed along the first edge; a first electrode that is disposed above the substrate; a second electrode that is disposed above the substrate; an electroluminescent layer at least a part of which is disposed between the first electrode and the second electrode; a barrier layer at least a part of which is disposed over the second electrode; and a protective layer that is in direct contact with the barrier layer, the protective layer having a gas barrier ability, the second electrode including: an upper portion that covers an upper part of the electroluminescent layer, a side portion that extends down from the upper portion, and a flange portion that extends from the side portion toward the second edge of the substrate and that does not contact the electroluminescent layer at a position closest to the second edge of the substrate.
