Laminate for a flexible device

PROBLEM TO BE SOLVED: To provide a laminate which has good releasability and, when being released from a glass substrate to obtain a flexible device, provides a polyimide film being hardly curled.SOLUTION: A laminate for a flexible device is a laminate of a glass substrate and a polyimide-based film. The adhesive strength between the glass substrate and the polyimide-based film is 7 N/cm or less. The curvature radius of the polyimide-based film released from the glass substrate is 30 mm or more. The polyimide-based film has a multilayer structure of two or more layers.
