2. Description of the Related Art For transporting a color filter for a substrate color liquid crystal display device and a glass substrate (including a completed panel) between device makers, various resins such as ABS resin and polyvinyl chloride are used. A glass substrate transport box including an injection molded body and its assembly is used. However, since these transport boxes are relatively heavy and have a poor impact-damping property, they are difficult to handle for transporting, stacking, and transporting glass substrates that are easily damaged. Therefore, a glass substrate carrying box made of foamed plastic such as foamed polyethylene or foamed polypropylene is used in place of these carrying boxes.

[0003]

The glass substrate is becoming larger due to the larger size of the liquid crystal display device, and the glass substrate carrying box is also becoming larger along with the larger glass substrate. However, due to the larger size of the glass substrate, the glass substrate easily bends under its own weight, and due to a slight displacement of the glass substrate in the glass substrate transport box, etc. It is a problem that expensive glass substrates are damaged in the glass substrate transporting processes such as the moving stage, the stacking stage and the transporting stage of the glass substrate transport box, resulting in enormous damage. It is an object of the present invention to eliminate the problems associated with a glass substrate carrying box of an opaque foamed molded article, which accompanies an increase in size of a conventional foam plastic glass substrate carrying box.
