PROBLEM TO BE SOLVED: To provide an optical adhesive sheet excellent in corrosion resistance with regard to a silver nanowire layer.SOLUTION: An optical adhesive sheet for a silver nanowire layer is a pressure sensitive adhesive sheet having an adhesive layer. The amount of acrylic acid ion extracted from the adhesive layer under a condition at 100°C for 45 minutes by pure water measured by an ion chromatograph method is 5 μg/g or less, with regard to 1 g of the adhesive layer. The adhesive layer is preferably an acrylic adhesive layer.SELECTED DRAWING: Figure 1 |
