  "abstract": "A manufacturing apparatus of a display device that prevents generation of bubbles between a display panel and a cover window is presented. The apparatus includes a first jig that includes a first portion including a center and a second portion that includes a bend on at least one side of the first portion, and where a cover window is received; a second jig that faces the first portion of the first jig, wherein the cover window and a display panel are disposed between the first jig and the second jig; and a stopper detachably provided adjacent to an end of the second portion of the first jig.",
  "claims": [
    "1. A manufacturing apparatus of a display device, comprising: a first jig including a first receiving side to which a cover window contacts; a second jig including a second receiving side to which a display panel contacts; clamps holding opposite ends of the display panel on the second jig; and stoppers between opposite ends of the cover window and the opposite ends of the display panel.",
    "2. The manufacturing apparatus of the display device of claim 1, wherein the opposite ends of the cover window are bent, and the stoppers are between lateral sides of the opposite ends of the cover window and the opposite ends of the display panel.",
    "3. The manufacturing apparatus of the display device of claim 1, wherein the stoppers prevent the opposite ends of the cover window from contacting the display panel when the clamps are separated from the display panel.",
    "4. The manufacturing apparatus of the display device of claim 1, wherein the stoppers are detachably provided adjacent to the opposite ends of the first jig.",
    "5. The manufacturing apparatus of the display device of claim 1, wherein the first jig comprises a stepped portion that is formed by cutting a corner of the first jig.",
    "6. The manufacturing apparatus of the display device of claim 5, wherein the stoppers comprise: a first limiter that protrudes toward a center of the first jig from the opposite ends of the first jig; and a second limiter that protrudes in a direction that is non-parallel to the protrusion direction of the first limiter and engages with the stepped portion of the first jig.",
    "7. The manufacturing apparatus of the display device of claim 1, further comprising a stopper driver that is capable of moving the stopper.",
    "8. The manufacturing apparatus of the display device of claim 1, wherein the stoppers are not bonded by an adhesive to the display panel.",
    "9. The manufacturing apparatus of the display device of claim 1, wherein the stoppers are made of one of plastic, rubber, and a metal.",
    "10. The manufacturing apparatus of the display device of claim 1, wherein the clamps support the display panel at lateral sides of the second jig."

  "description_excerpt": "The present disclosure relates to an apparatus for manufacturing a display device, and a method for manufacturing the display device. More particularly, the present disclosure relates to an apparatus for manufacturing a display device by attaching a display panel and a cover window to each other, and a method for manufacturing the display device.\n\nRecently, a display device using a plastic substrate has been developed to offer advantages such as light weight, robustness against impact, and flexibility. The flexible display device can be folded or rolled in a scroll-like manner, allowing the flexible display device to be utilized in various fields.\n\nThe flexible display device includes a display element that is formed on a flexible substrate. An organic light emitting display element, a liquid crystal display element, and the like may be included as a display element that can be used in the flexible display device.\n\nSuch display elements commonly include a thin film transistor. Accordingly, the flexible substrate undergoes several thin film processes. The flexible substrate having undergone the thin film processes is sealed by an encapsulation layer. The flexible substrate, the thin film transistor formed in the flexible substrate, and the encapsulation layer form a display panel of the display device.\n\nIn general, a cover window that protects the display panel is attached to the entire surface of the display panel. In this case, an adhesive is provided between the display panel and the cover window such that the display panel and the cover window are bonded to each other.",
