The present invention relates to a laminate and a device fabricated using the laminate. The laminate includes a first polyimide resin layer between a carrier substrate and a second polyimide resin layer, wherein the first polyimide resin layer has a coefficient of thermal expansion (CTE) equal to or lower than the CTE of the second polyimide-based resin layer at a temperature of 100 to 200?
