PROBLEM TO BE SOLVED: To provide a composition for forming a protective film capable of preventing ion migration from a conductive film containing silver.SOLUTION: There is provided a composition for forming a protective film which comprises: a reducing compound (A) selected from the general formulas (A1) to (A3); a compound (B) selected from the group consisting of a triazole structure, a thiazole structure and a benzimidazole structure; a transparent resin (C); and a polymerizable compound (D). (Rto Rrepresent an aliphatic hydrocarbon group which may have a hydrogen atom, a hydroxyl group and an oxygen atom or an aromatic hydrocarbon group which may have an oxygen atom and the total number of carbon atoms contained in each group of Rto Ris 4 or more; Rto Rrepresent an aliphatic hydrocarbon group or an aromatic hydrocarbon group and the total number of carbon atoms contained in each group of Rto Ris 6 or more; and in the general formula (A3), Rto Rrepresent an alkyl group which may contain a hetero atom or an aryl group which may contain a hetero atom and the total number of carbon atoms contained in each group of Rto Ris 6 or more.) |
