Display device, apparatus for manufacturing the same, and method of manufacturing the display device

A method of manufacturing a display device using a display device manufacturing apparatus comprising a stage, a fixing unit, and a bonding unit disposed on the stage and comprising a position detection sensor, a light irradiation unit, and a resin supply unit disposed between the position detection sensor and the light irradiation unit, the method comprising:

• disposing a display module on the stage, the display module comprising a display panel comprising an active area and a peripheral area, a first side edge, a first flexible circuit board disposed in the peripheral area near the first side edge, a window disposed on the display panel, and an optical film disposed between the display panel and the window;
• aligning the display module such that the first side edge of the display module is disposed under the bonding unit;
• moving the position detection sensor along the first side edge of the display module to sense a first coating path;
• moving the resin supply unit along the sensed first coating path to coat a first filling agent between the window and the display panel;
• and
• moving the light irradiation unit along the sensed first coating path to cure the coated first filling agent to form a first filling layer.
