  "abstract": "A display device is provided. When the display device is attached to a wall, a space between the display device and the wall is not exposed externally, thereby improving the aesthetic quality of the design. The angle of attachment of the display device is simply adjustable, thereby improving user convenience.",
  "claims": [
    "1. A display device, comprising: a middle cabinet comprising: a first support portion surrounding one edge of a display panel; and a second support portion extending inward from an inner surface of the first support portion, a rear surface of the display panel being seated on a front surface of the second support portion; a back cover on a rear surface of the second support portion; a cabinet cover supported on the inner surface or an outer surface of the first support portion, the cabinet cover being configured to slide in a direction of a front surface of the display panel or in an opposite direction to be in close contact with a wall; and an elastic member between and directly contacting the back cover and the cabinet cover to directly elastically support the cabinet cover via holding portions on the back cover and the cabinet cover.",
    "2. The display device according to claim 1, further comprising: a first fixing member on a rear surface of the back cover; and a second fixing member on the wall to support the first fixing member.",
    "3. The display device according to claim 2, wherein: the first fixing member comprises a spherical ball portion protruding in a direction of the rear surface of the back cover; and the second fixing member comprises a fixing portion fixed to the wall, a hollow cylinder portion extending from the fixing portion, and a housing portion at a distal end of the hollow cylinder portion to surround the ball portion, thereby supporting tilting movements.",
    "4. The display device according to claim 3, wherein the second fixing member further comprises: a support member on the hollow cylinder portion to be in close contact with the ball portion; and an elastic support member between the support member and the fixing portion to elastically support the support member toward the ball portion.",
    "5. The display device according to claim 4, wherein: the support member has a sliding protrusion provided on an outer surface thereof to be slide-supported in the hollow cylinder portion; and the hollow cylinder portion has a sliding groove allowing the sliding protrusion inserted therein to slide.",
    "6. The display device according to claim 5, wherein: one of an outer circumference of the ball portion and a front surface of the support member comprises one or more convex support protrusions; and the other of the outer circumference of the ball portion and the front surface of the support member comprises one or more support recesses having a concave shape conforming to the convex support protrusions.",
    "7. The display device according to claim 6, wherein the cabinet cover comprises: a side support portion supported on the inner surface or the outer surface of the first support portion; and a wall support portion supported on and in close contact with the wall.",
    "8. The display device according to claim 7, wherein: one of the first support portion and the side support portion has a guide protrusion; and the other of the first support portion and the side support portion has a guide groove allowing the guide protrusion inserted therein to slide.",
    "9. The display device according to claim 8, wherein one or both of the back cover and the wall support portion comprise holding portions preventing the elastic member from being dislodged by fixing the elastic member in position.",
    "10. The display device according to claim 1, wherein the cabinet cover comprises: a side support portion supported on the inner surface or the outer surface of the first support portion; and a wall support portion supported on and in close contact with the wall.",
    "11. The display device according to claim 10, wherein: one of the first support portion and the side support portion has a guide protrusions; and the other of the first support portion and the side support portion has a guide groove allowing the guide protrusion inserted therein to slide.",
    "12. The display device according to claim 10, wherein the holding portions prevent the elastic member from being dislodged by fixing the elastic member in position.",
    "13. The display device according to claim 10, wherein the elastic member directly contacts the wall support portion of the cabinet cover.",
    "14. The display device according to claim 1, wherein: one of the first support portion and the cabinet cover has a guide protrusion; the other of the first support portion and the cabinet cover has a guide groove allowing the guide protrusion inserted therein to slide; the guide protrusion has fitting protrusions protruding in opposite directions from the guide protrusion; and the guide groove has fitting grooves conforming to the fitting protrusions.",
    "15. The display device according to claim 1, further comprising: a bonding pad between the display panel and the second support portion of the middle cabinet; and wherein the elastic member is provided where the bonding pad, the second support portion, and the back cover overlap."

  "description_excerpt": "The present disclosure relates to a display device. More particularly, the present disclosure relates to a display device that can be attached to a wall, such that a space between the display device and the wall is not exposed externally, thereby improving a sense of unity between the wall and the display device, as well as the aesthetic quality of the design, and such that the angle of attachment of the display device is simply adjustable, thereby improving user convenience.\n\nGenerally, research into flat panel display devices, such as liquid crystal display (LCD) devices, plasma display devices, field emission display (FED) devices, and organic light-emitting display devices, has been actively undertaken. In this regard, LCD devices and organic light-emitting display devices have come to prominence through allowing for mass production, having ease of driving, as well as the realization of high definition.\n\nFIG. 1 is a side elevation view illustrating a related-art display device attached to a wall.\n\nIn the related art, as illustrated in FIG. 1, a wall attachment device 20 is attached to a wall 30, and a wall display device 10 is connected to the wall attachment device 20 using a holder, or the like, provided on the rear surface thereof, such that the wall display device 10 can be attached to the wall 30.\n\nHowever, it may be difficult for a user to attach the related-art wall attachment device 20 for the display device 10 to the wall by him or herself, since the wall attachment device 20 may be relatively large and heavy.",
