  "claims": [
    "1. A plate loading device, comprising: an upper frame facing and spaced-apart from a lower frame in a first direction; a plurality of side members disposed between the upper frame and the lower frame and extending in the first direction, wherein the plurality of side members include a first side member and a second side member facing each other, and the first side member and the second side member each comprise a plurality of holes; and a plurality of supporting parts that pass through the plurality of holes, respectively, the plate loading device to load a plurality of plates sequentially in the first direction, wherein each of the plurality of supporting parts comprises: a body penetrating one hole of the plurality of holes and movable through the hole; a head connected to an end of the body and having a width greater than both a largest width of the hole and a width of the body; and an end part connected to another end of the body and having a width greater than both a largest width of the hole and a width of the body, the head is heavier than the end part, and ones of the plurality of supporting parts that support one of the plurality of plates protrude inward more than others of the plurality of supporting parts disposed above the ones of the plurality of supporting parts that support the one of the plurality of plates.",
    "2. The plate loading device of claim 1, wherein the plurality of holes are arranged in the first direction.",
    "3. The plate loading device of claim 2, wherein spacing between neighboring ones of the plurality of holes arranged in the first direction is constant.",
    "4. The plate loading device of claim 1, wherein the body is movable in the hole in a direction passing through the hole.",
    "5. The plate loading device of claim 1, wherein the head includes a portion having a greater width than the largest width of the hole, and a center of mass of the supporting part is disposed at the head.",
    "6. The plate loading device of claim 5, wherein a lower surface of each of the plurality of plates loaded into the plate loading device directly contacts the head of ones of the plurality of supporting parts.",
    "7. The plate loading device of claim 1, wherein the plurality of side members further comprises a plurality of third side members disposed between the plurality of supporting parts that face each other, and a spacing between ones of the plurality of third side members is smaller than a length of an edge of each of the plurality of plates to be loaded into the plate loading device.",
    "8. The plate loading device of claim 7, wherein during a loading process of the plurality of plates, the edge of the plurality of plates slides in contact with the plurality of third side members.",
    "9. The plate loading device of claim 1, further comprising: a supporter disposed under the lower frame to support the lower frame, wherein the supporter includes a bottom surface and an inclined surface having an inclination angle of greater than 0 degrees with respect to the bottom surface.",
    "10. The plate loading device of claim 9, wherein the first side member and the second side member each extend in a direction perpendicular to the inclined surface.",
    "11. The plate loading device of claim 4, wherein a shape of the body is selected from a cylinder, an elliptic cylinder, and a polygonal prism.",
    "12. A plate loading device comprising: a plurality of first side members facing a plurality of second side members, wherein a plurality of holes are disposed in the plurality of first side members and the plurality of second side members; a plurality of third side members disposed between the plurality of first side members and the plurality of second side members; and a plurality of supporting parts respectively disposed in the plurality of holes disposed in the plurality of first side members and the plurality of second side members, wherein each of the plurality of first side members, the plurality of second side members, and the plurality of third side members extends in a first direction in which each of a plurality of plates is loaded, and each of the plurality of supporting parts is movable in a corresponding one of the plurality of holes in a second direction perpendicular to the first direction, wherein each of the plurality of supporting parts comprises: a body penetrating one hole of the plurality of holes and movable through the hole; a head connected to an end of the body and having a width greater than both a largest width of the hole and a width of the body; and an end part connected to another end of the body and having a width greater than both a largest width of the hole and a width of the body, the head is heavier than the end part, and ones of the plurality of supporting parts supporting one of the plurality of plates protrude inward more than others of the plurality of supporting parts that are positioned above the ones of the plurality of supporting parts that support the one of the plurality of plates.",
    "13. The plate loading device of claim 12, wherein during a loading process of each of the plurality of plates, an edge of each of the plurality of plates slides in contact with the plurality of third side members."

  "description_excerpt": "1. Technical Field The disclosure relates to a plate loading device and a plate loading method using the same. 2. Description of the Related Art Display devices such as an organic light emitting display and a liquid crystal display include a display panel manufactured by forming several layers and elements on a substrate. Recently, a flexible display panel and a flexible display device including the same have been developed. The flexible display device may be classified into a bendable display device, a foldable display device, and a rollable display device depending on a use or a shape. To make the display device flexible, the display device may include a thin glass substrate or plate such as a window. In addition to the flexible display devices, a thin plate may be used as substrates or windows to realize the thin display device. During the manufacturing process of the display device, defects such as cracks during loading or transshipping the thin plate on the loading device for various process steps may readily occur.\n\nThe above information disclosed in this Background section is only for enhancement of understanding of the background of the invention, and therefore it may contain information that does not form the prior art under 35 U.S.C. § 102 that may be already known in this country to a person of ordinary skill in the art.\n\nEmbodiments of the disclosure are to provide a plate loading device and a plate loading method using the same, which may reduce the occurrence of defects such as cracks during loading or transshipping the plate during the manufacturing process of the display device.",
