First claim
Opening claim text (preview).
The invention claimed is: 1. A substrate for flexible device, including a stainless steel sheet, an oxide layer on a surface of the stainless steel sheet, and a glass layer of electrically-insulating bismuth-based glass in a form of layer on a surface of the oxide layer, wherein a chromium concentration at a point distanced by 20 nm in a thickness direction of the oxide layer from an interface between the oxide layer and the glass layer is not less than 30 atomic %. 2. The substrate for flexible device according to claim 1 , wherein the oxide layer has a thickness of not less than 30 nm. 3. The substrate for flexible device according to claim 1 , wherein the oxide layer has a thickness of not less than 80 nm. 4. The substrate for flexible device according to claim 1 , wherein the chromium concentration at the point distanced by 20 nm in the thickness direction of the oxide layer from the interface between the oxide layer and the glass layer is not less than 50 atomic %. 5. The substrate for flexible device according to claim 1 , wherein the bismuth-based glass contains Bi 2 O 3 , ZnO and B 2 O 3 .
