Method of manufacturing display device

A method of manufacturing a display device, the method comprising:

• discharging ink onto a substrate including a color filter area, a dummy accommodation area and a main partition wall for partitioning the color filter area and the dummy accommodation area adjacent to the color filter area;
• generating main position information by detecting a position of first erroneous ink discharged on the main partition wall;
• generating main color information by detecting a color of the first erroneous ink;
• comparing the color of the first erroneous ink with a color of the ink discharged to the color filter area, based on the main color information;
• bringing a hydrophobic plate disposed adjacent to the first erroneous ink into contact with the main partition wall based on the main position information;
• and
• then moving the hydrophobic plate in a direction to the color filter area to accommodate the first erroneous ink in the color filter area, when the color of the first erroneous ink is identical to the color of the ink discharged to the color filter area.
