Abstract: The present disclosure is directed to a coating composition including a graphene oxide and a solvent. At least one of a carboxyl group and an epoxide group of the graphene oxide is functionalized by an amine. The amine has an activation energy to an epoxide group of the graphene oxide of about −3 kcal/mol to about 8 kcal/mol. A method of forming a stacked structure using the coating composition is provided. A method of manufacturing a display device using the coating composition is provided.

Abstract: An apparatus and a method for manufacturing a display device are provided. An apparatus for manufacturing a display device includes a first unit configured to remove impurities of a support substrate, a second unit configured to form a sacrificial layer on the support substrate, a third unit configured to form a flexible substrate on the sacrificial layer, and a fourth unit configured to form a display unit on the flexible substrate. The second unit includes a moving unit movable in a first direction to receive the support substrate, a first supply nozzle configured to spray a solution onto the support substrate to coat a graphene oxide layer, and a second supply nozzle configured to dry the graphene oxide layer coated on the support substrate while removing a portion of the graphene oxide layer, to form the sacrificial layer.
