Abstract
Disclosed are a supporting substrate for manufacturing a flexible information display device capable of easily separating the flexible information display device from the supporting substrate without deforming or damaging the flexible information display device, a manufacturing method thereof, and a flexible information display device manufactured thereby. The supporting substrate for manufacturing a flexible information display device includes: a coating layer formed therein with a plurality micro-protrusions formed on the supporting substrate; and a temporary bonding/debonding layer formed on the coating layer and including an adhesive material mechanically interlocked with and bonded to the supporting substrate through Van der Waals bonding force. The method provides a method capable of economically manufacturing the display device having a high resolution while reviewing a cost competitive force by reducing a device investment cost and improving the yield rate in the flexible flat panel information display device.
