LAMINATE AND METHOD FOR MANUFACTURING FLEXIBLE DEVICE

摘要

The present invention provides a laminate which exhibits excellent adhesiveness between a heat resistant resin film having a flexible substrate layer and an inorganic substrate, and in which the flexible substrate layer can be separated from the inorganic substrate easily and in a short amount of time. A laminate 100 has an inorganic substrate 1 and a heat resistant resin film 2 formed on the inorganic substrate, and is characterized by the following: (1) the heat resistant resin film 2 has a flexible substrate layer 21 and a sacrificial layer 22 provided on an outer edge of the flexible substrate layer; (2) the adhesive strength between the flexible substrate layer 21 and the inorganic substrate 1 is 2 N/cm or less; (3) the adhesive strength between the sacrificial layer 22 and the inorganic substrate 1 is greater than 2 N/cm; and (4) the adhesive strength between the sacrificial layer 22 and the inorganic substrate 1 is made to be 2 N/cm or less by post-processing.
