NOVELTY - A support substrate for temporarily adhesively fixing a flexible substrate in a flexible display manufacturing process, is manufactured by supplying adhesion-inducing material containing amine-based silicon on one surface of support substrate, applying plasma to form an adhesion-inducing thin film, supplying adhesion solution containing two-dimensional plate-shaped inorganic material that is electrostatically coupled to adhesion-inducing material included in the adhesion-inducing thin film to form adhesion layer on adhesion-inducing thin film, and heat-treating the adhesion-inducing thin film and the adhesion layer formed on the support substrate. USE - Manufacture of support substrate for temporarily adhesively fixing a flexible substrate in a flexible display manufacturing process. ADVANTAGE - The support substrate can be manufactured at a low heat treatment temperature and has the effect of minimizing the possibility of generating contamination of the substrate. In addition, cost and maintenance of the device can be significantly reduced. The support substrate can be easily separated by mechanical force after the production of the flexible display is completed, while minimizing the possibility of defects and damage to the flexible display, and improving productivity.
