Abstract
An ink leveling device includes a stage on which a target substrate is disposed, base frames disposed at sides of the stage, moving members coupled to the base frames and movable upward and downward, and at least one plate coupled to the moving members and disposed to press the target substrate. Light-emitting element ink is disposed on the target substrate.
Claims20
An ink leveling device comprising:
- a stage on which a target substrate is disposed, wherein light-emitting element ink is disposed on the target substrate;
- base frames disposed at sides of the stage;
- moving members coupled to the base frames and movable upward and downward;
- and
- at least one plate coupled to the moving members and disposed to move relative to the target substrate and light-emitting element ink to press the target substrate.

A method of manufacturing a display device, the method comprising:
- disposing light-emitting element ink including light-emitting elements on a target substrate;
- pressing the target substrate by moving a plate relative to the target substrate and the light-emitting element ink;
- after pressing the target substrate, aligning the light-emitting elements by forming an electric field on the target substrate and irradiating ultraviolet light on the target substrate;
- and
- after aligning the light-emitting elements, separating the plate from the target substrate.
