First claim

Opening claim text (preview).

What is claimed is: 1. An electron emission element comprising: a lower electrode; a surface electrode; a silicone resin layer disposed between the lower electrode and the surface electrode, wherein the surface electrode includes a silver layer, and the silver layer is in contact with the silicone resin layer. 2. The electron emission element according to claim 1 , wherein the silver layer is a silver sputtering layer or a silver-deposited film. 3. The electron emission element according to claim 1 , wherein a thickness of the silicone resin layer is 0.5 μm or more and 1.25 μm or less, and a thickness of the silver layer is more than 5 nm and 30 nm or less. 4. The electron emission element according to claim 1 , wherein the surface electrode is a laminated electrode in which the silver layer and a gold layer or a platinum layer are laminated. 5. The electron emission element according to claim 4 , wherein a thickness of the gold layer or a thickness of the platinum layer is 10 nm or more and 20 nm or less. 6. The electron emission element according to claim 1 , further comprising a substrate, wherein the lower electrode is disposed on the substrate, the silicone resin layer is disposed on the lower electrode, and the surface electrode is disposed on the silicone resin layer.
