Description

  The present invention relates to a frame for conveying a plate glass, a glass substrate and a color filter substrate used in a liquid crystal display device which is a processed product thereof.

Conventionally, when storing and transporting a color filter substrate having projections such as a black matrix, a colored layer, a transparent conductive film layer and a spacer on the surface of a glass substrate which is a plate glass and its processed product, the surface of the glass substrate is damaged. In order to protect from damage, a box-shaped storage container that can store glass substrates in parallel at a predetermined interval has been used so that the glass substrates do not contact each other.
