Patent ID: 7977873

Claim:
An EL device comprising: a substrate; a first electrode layer on the substrate; an insulating layer on the first electrode layer, comprising an organic material and including an opening corresponding to a pixel; a first protective layer covering the insulating layer; an organic layer on the first protective layer and the first electrode layer in the opening, including a light-emitting layer; a second electrode layer on the organic layer; a second protective layer on the second electrode layer, wherein the second protective layer covers edges of the organic layer and the second electrode layer and extends to the outside of the region where the organic layer and the second electrode layer are formed so as to contact the first protective layer; a plurality of pixel regions where organic light-emitting elements are arranged, each of which comprises the first electrode laver, the organic layer, and the second electrode layer; and a partition wall on the insulating laver, separating adjacent pixel regions, wherein an entire surface of the partition wall is covered with the first protective layer, and the second protective layer covers the first protective layer to be in direct contact with an upper surface of the first protective layer on the partition wall.
