Abstract
An EL device includes a substrate; a first electrode layer; an insulating layer having 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; a second electrode layer on the organic layer; and 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 forming region of the organic layer and the second electrode layer to contact the first protective layer.
