Abstract
The present invention relates to a laminate and a device fabricated using the laminate. The laminate includes a debonding layer including a polyimide resin having a similarity score not greater than 0.5, as calculated by Equation 1 defined in the detailed description, between a carrier substrate and a flexible substrate. According to the present invention, the flexible substrate can be easily separated from the carrier substrate without the need for further processing such as laser or light irradiation. Therefore, the use of the laminate facilitates the fabrication of the device having the flexible substrate. The device may be, for example, a flexible display device. In addition, the device can be prevented from deterioration of reliability and occurrence of defects caused by laser or light irradiation. This ensures improved characteristics and high reliability of the device.
