First claim

Opening claim text (preview).

What is claimed is: 1. An electroluminescent device comprising: a substrate; an electroluminescent element provided on the substrate; and a sealing film configured to seal the electroluminescent element; wherein the sealing film includes a first inorganic film, a second inorganic film and a leveled film, wherein the first inorganic film, the leveled film and the second inorganic film are provided in that order from the substrate, the second inorganic film covers a surface and an edge of the leveled film, a peripheral portion of the first inorganic film is thick, a liquid repellent layer is provided covering the sealing film, the liquid repellent layer is provided covering an edge of the first inorganic film, a peripheral surface of the first inorganic film, an edge of the second inorganic film, and a surface of the second inorganic film, the peripheral surface of the first inorganic film being uncovered by the second inorganic film, and the peripheral portion of the first inorganic film overlaps the edge of the leveled film and the edge of the second inorganic film. 2. The electroluminescent device according to claim 1 , wherein a thickness of a peripheral portion of the first inorganic film is not less than 50 nm. 3. The electroluminescent device according to claim 1 , wherein fluorine is used in the liquid repellent layer. 4. An electroluminescent device comprising: a substrate; an electroluminescent element provided on the substrate; and a sealing film including a third inorganic film and configured to seal the electroluminescent element; wherein the sealing film includes a first inorganic film, a second inorganic film and a leveled film, the third inorganic film, the leveled film, the second inorganic film and the first inorganic film are provided in that order from the substrate, the first inorganic film covers an edge of the third inorganic film, an edge of the leveled film and an edge of the second inorganic film, the first inorganic film is configured in a frame shape and has an opening which overlaps a pixel area, a peripheral portion of the first inorganic film is thick, a liquid repellent layer is provided covering the sealing film, and the liquid repellent layer is provided covering an edge of the first inorganic film and a surface of the second inorganic film. 5. The electroluminescent device according to claim 4 , wherein a thickness of a peripheral portion of the first inorganic film is not less than 50 nm. 6. The electroluminescent device according to claim 4 , wherein fluorine is used in the liquid repellent layer. 7. The electroluminescent device according to claim 4 , wherein the liquid repellent layer covers the edge of the first inorganic film, a surface of the first inorganic film and the surface of the second inorganic film, the surface of the second inorganic film being exposed from the opening.
