aligning the display module such that the first side edge 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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the position detection sensor, the resin supply unit, and the light irradiation unit are arranged in the bonding unit such that the resin supply unit is disposed between the position detection sensor and the light irradiation unit, and the resin supply unit and the position detection sensor maintain a first distance from each other while moving along the first coating path in the coating of the first filling agent. ### Claim 3 (depends on 2) The method of claim 2, wherein the light irradiation unit and the resin supply unit maintain a second distance from each other while moving along the first coating path in the forming of the first filling layer. ### Claim 4 (depends on 1) The method of claim 1, wherein the coating of the first filling agent comprises coating the first filling agent in a space defined by the display panel, the window facing the display panel, and a side surface of the optical film that is exposed. ### Claim 5 (depends on 1) The method of claim 1, wherein the first coating path corresponds to a shape of the first side edge of the display module and is positioned between the window and the display panel. ### Claim 6 (depends on 1) The method of claim 1, wherein the display module further comprises a second flexible circuit board disposed in the peripheral area near a second side edge of the display panel and spaced apart from the first flexible circuit board, and after the forming of the first filling layer, the method further comprises: aligning the display module such that the second side edge of the display module is disposed under the bonding unit; moving the position detection sensor along the second side edge of the display module to sense a second coating path; moving the resin supply unit along the sensed second coating path to coat a second filling agent between the window and the display module; and moving the light irradiation unit along the sensed second coating path to cure the coated second filling agent to form a second filling layer. ### Claim 7 (depends on 6) The method of claim 6, wherein the second coating path corresponds to a shape of the second side edge of the display module and is positioned between the window and the display panel.
