A method of manufacturing a display device includes forming a thin film transistor on an insulating substrate, forming an electrode which is electrically connected with the thin film transistor, forming a wall which surrounds the electrode, supplying a first solvent to the electrode that is surrounded by the wall, and supplying ink which comprises an organic material and a second solvent to the electrode which has previously received the first solvent. Thus, the manufacturing method produces a display device which has a uniform organic layer.
