SUBSTRATE FOR TRANSPARENT ELECTRODE LAMINATION AND ORGANIC ELECTROLUMINESCENT ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a substrate for transparent electrode lamination, capable of having sufficiently high heat resistance and sufficiently high flexibility.SOLUTION: The substrate for transparent electrode lamination includes a glass substrate with a thickness of 5-100 μm and a polyimide layer with a thickness of 1-50 μm laminated on a surface of the glass substrate. The polyimide layer is a layer comprising a polyimide having a repeating unit represented by general formula (1) [where R, R, and Reach independently represent a hydrogen atom or the like; Rrepresents a 6-40C aryl group; and n represents an integer of 0-12].SELECTED DRAWING: None
