Apparatus and method for manufacturing display device

A method of manufacturing a display device, comprising:

• preparing a support substrate;
• forming a sacrificial layer by spraying a solution, which is bonded to the support substrate by van der Waals bonding, onto the support substrate, thus coating a graphene oxide layer, and then drying the graphene oxide layer while removing a portion of the graphene oxide layer;
• forming a flexible substrate on the sacrificial layer;
• forming a display unit on the flexible substrate;
• forming a thin-film encapsulation film on the display unit;
• and
• separating the support substrate from the flexible substrate.

An apparatus for manufacturing a display device, comprising:

• 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,
• wherein the second unit comprises:
• a moving unit movable in a first direction to receive the support substrate;
• a first supply nozzle configured to spray a solution, which is bondable to the support substrate by van der Waals bonding, 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,
• wherein the first supply nozzle and the second supply nozzle are spaced apart from each other by a distance and are coupled to each other in line.
