Abstract
According to the present invention, a stack comprises, between a carrier substrate and a flexible substrate layer, a peeling power adjustment layer comprising polyimide, which has a refractive index higher than that of the flexible substrate layer, so that a flexible substrate can be more easily peeled from a carrier substrate layer, and thus a flexible element can be manufactured without damage to the element through a simpler process.
