  "abstract": "The described technology generally relates to a method of manufacturing a display device and a manufacturing apparatus for the same. In one aspect, the method includes placing a carrier, in which a display panel is formed, into a film attachment portion such that the carrier is pulled onto a carrier adsorption surface of a first stage. The method also includes attaching a first protection film onto a first surface of the display panel in the film attachment portion, wherein the first surface is located opposite to a second surface of the display panel that faces the carrier. The method also includes first transferring the first stage to a carrier separation portion, separating the display panel from the carrier, and second transferring the display panel to a second stage such that the attached protection film is pulled onto a second film adsorption surface of the second stage.",
  "claims": [
    "1. A method of manufacturing a display device, the method comprising: placing a carrier, in which a display panel is formed, into a film attachment portion such that the carrier is pulled onto a carrier adsorption surface of a first stage; attaching a first protection film onto a first surface of the display panel in the film attachment portion, wherein the first surface is located opposite to a second surface of the display panel that faces the carrier; first transferring the first stage to a carrier separation portion; separating the display panel from the carrier; second transferring the display panel to a second stage such that the attached protection film is pulled onto a second film adsorption surface of the second stage; third transferring the second stage, on which the attached protection film is pulled from the carrier separation portion, to a transfer portion; separating the display panel from the second stage; placing the display panel on the transfer portion such that the second surface faces the transfer portion; removing the carrier from the first stage after separating the display panel from the carrier; fourth transferring the display panel to the film attachment portion such that the first protection film is pulled onto a first film adsorption surface of the first stage so that the display panel is supported via the first stage; and attaching a second protection film onto the second surface of the display panel in the film attachment portion.",
    "2. The method of claim 1, further comprising rotating the second stage, between the second transferring and the third transferring.",
    "3. The method of claim 1, further comprising rotating the second stage, between the third transferring and the separating.",
    "4. The method of claim 1, further comprising rotating the first stage, between the removing and the fourth transferring.",
    "5. The method of claim 1, wherein the transfer portion is positioned between the film attachment portion and the carrier separation portion.",
    "6. The method of claim 1, wherein the film attachment portion comprises a first chamber body including a first main entrance located at one side thereof and an auxiliary entrance located at another side thereof, wherein the display panel is configured to be inserted or removed through the first main entrance or the auxiliary entrance, wherein the carrier separation portion comprises a second chamber body comprising a second main entrance located at one side thereof, wherein the display panel is further configured to be inserted or removed through the second main entrance, wherein the second main entrance corresponds to the auxiliary entrance of the film attachment portion, wherein the first transferring is performed through the auxiliary entrance of the film attachment portion and the second main entrance of the carrier separation portion, wherein the third transferring is performed through the second main entrance of the carrier separation portion, and wherein the fourth transferring is performed through the auxiliary entrance of the film attachment portion.",
    "7. The method of claim 1, wherein one surface of the first stage includes the carrier adsorption surface and the other surface of the first stage includes the first film adsorption surface.",
    "8. The method of claim 7, wherein a plurality of first and second adsorption holes are respectively formed in the first film adsorption surface and carrier adsorption surface, and wherein the number of the first adsorption holes is greater than the number of the second adsorption holes."

  "description_excerpt": "Field The described technology generally relates to a method of manufacturing a display device and a manufacturing apparatus for the same. Description of the Related Technology In general, during the manufacturing of a flat panel display device, a protection film is attached so as to protect the display surface of a display panel or a reverse side thereof. The protection film can be intended to be temporarily attached during manufacturing and yet remain attached in the final product.\n\nOne inventive aspect relates to a method of manufacturing a display device having a simplified configuration and a manufacturing apparatus for the same. Another aspect is a display manufacturing apparatus that includes a film attachment unit including a first chamber body including a first main entrance located at one side thereof and an auxiliary entrance located at another side thereof, and allowing protection films to be attached to a display, wherein the display is insertable or removable through the first main entrance or the auxiliary entrance; a carrier separation unit including a second chamber body including a second main entrance located at one side thereof, and separating the display from the carrier supporting the display, wherein the display is insertable or removable through the second main entrance; a transfer disposed between the film attachment unit and the carrier separation unit and for allowing the display separated from the carrier to be seated; a first stage for going and ...",
