Multilayer structure, device using same, and manufacturing method therefor

摘要

Provided is a novel multilayer structure which can be used to protect a device, and a device which uses this novel multilayer structure. The disclosed multilayer structure is a multilayer structure including a substrate and a barrier layer laminated on the substrate. The substrate has tension equal to or greater than 2,000 N/m when there is 3% distortion in at least one direction. The barrier layer includes a reaction product (R). This reaction product (R) is obtained by reacting at least a metal oxide (A) with a phosphorus compound (B). The wavenumber (n
