1. A window coating method comprising:
providing a window on a window coating jig comprising a base part and a stage, wherein the base part has a blow hole and a suction hole defined therein, the stage has a blow groove connected to the blow hole, a suction groove connected to the suction hole, and a vent opening formed in an outer wall, and the blow groove, the suction groove, and the vent opening are defined in the stage;
providing a downward air flow to the suction hole by an air-flow-generating unit to fix the window on the stage;
providing an upward air flow to the blow hole by the air-flow-generating unit to form an air pocket which is formed due to a difference in air pressure between the vent opening and the blow groove; and
applying a coating solution on the window,
wherein a pressure of air which is provided from the blow hole is greater than a pressure of air which is discharged from the vent opening to an outside.
