Description

  The present invention relates to a display member transport case used for storing and transporting a glass substrate used in a liquid crystal display or the like and a panel member or the like formed by combining a polarizing film with the glass substrate.

As the size of recent display, even a glass substrate used in this size is advanced to 2160 × 2400 mm ² of the eighth generation, and 2400 × 2800 mm ² of the ninth generation.

  Conventionally, the surface of the glass substrate was covered with a slip sheet or film to prevent the surface of the glass substrate from being stained and scratched during storage / transportation. Due to the increase in size, static electricity is remarkably generated when the interleaf paper or film is peeled off, and processing of the peeled interleaf paper or film is required.

  Therefore, between the left and right surfaces of the cubic frame, a linear object such as a metal wire, wire, or a thin string made of synthetic resin fiber is stretched in the horizontal direction as a horizontal rail for mounting, A transfer case on which a glass substrate is mounted has been proposed (see, for example, Patent Document 1).

  In the transport case disclosed in Patent Document 1, contact with the glass substrate is reduced by making the horizontal rail for mounting into a linear body, and further, various properties such as durability, heat resistance, chemical resistance, etc. The linear body is covered with super engineering plastic such as polyetheretherketone, which is excellent and has non-slip characteristics, to prevent the surface of the glass substrate from getting dirty and scratched.
