Abstract
A method of manufacturing a display device includes forming a thin film transistor on an insulating substrate, forming an electrode electrically connected to the thin film transistor, forming a wall surrounding the electrode, ejecting ink comprising an organic material and a first solvent on the electrode, and supplying a second solvent to the ink. Thus, an organic layer of uniform quality is formed in the display device formed by the method.
Claims20
A method of manufacturing a display device, the method comprising:
- forming a plurality of areas on an insulating substrate of the display device;
- sequentially ejecting ink including an organic material and a first solvent within each area;
- and,
- supplying a second solvent to the ink to form an organic layer having substantially uniform quality across the display device,
- wherein supplying the second solvent includes supplying more of the second solvent to an earlier-ejected portion of the ink than to a later-ejected portion of the ink;
- wherein supplying the second solvent includes supplying the second solvent after ejecting the ink on all the plurality of areas.
