Problems solved by technology

[0005] However, recently, it is required to manufacture larger color filter substrates. If these substrates are stored at predetermined intervals as in the past, larger storage containers and storage spaces are required. In addition, they are easily broken during transportation. In practice, it is difficult to store and transport using storage containers like the above

Embodiment 1

[0123] Hereinafter, it will explain in detail based on an Example.

[0124] After the surface of the colored layer side of the color filter substrate with a size of 1500 mm in length and 1800 mm in width is coated with a 10% aqueous solution of ゴ-セノ-ル NK-05 manufactured by Nippon Synthetic Chemical Industry Co., Ltd. with a roll coater, it is dried in an oven at 80°C Dry in medium for 10 minutes to obtain a protective layer consisting of a coating layer with a thickness of 5 μm.

[0125] In order to prevent the adjacent substrates from sticking together as if they were integrated due to the high planar accuracy of the substrates, between the adjacent color filter substrates, HZ50 (polyethylene film) (length 1520 mm × width) made by Toseiro Co., Ltd. was sandwiched. 1780mm), while storing 200 color filter substrates protected by the coating layer on a dedicated pallet that can be stored in a state that can be tilted at an angle of 15 degrees from the vertical state.

Abstract

A layered body of color filter substrates, where the color filter substrates used for liquid crystal display devices etc. are protected from flaws and damage, and which is advantageous for storage and transportation. A removable protective layer constituted of an adhesive film and a coating layer is provided on the surface on the colored layer side of a color filter substrate whose basic structures such as black matrices, colored layers, a transparent electrode, and spacers are formed on the surface of a glass substrate. Color filter substrates, on the colored layer side of each of which the protective layer is provided, are layered over each other while being prevented from coming into contact with each other with separation bodies such as paper and resin film in between.

Description

technical field [0001] The present invention relates to a color filter substrate that is used in a liquid crystal display device and the like and is advantageous in storage and transportation, a laminate thereof, and a method of using the color filter substrate. Background technique [0002] Usually, the color filter substrate is stored and transported in a state where protrusions such as a black matrix layer, a colored layer, a transparent conductive film layer, and a spacer are formed on the surface of a glass substrate. [0003] In the past, when storing and transporting color filter substrates, in order to protect the surface of the color filter substrates from scratches and breakages, boxes that can store color filter substrates side by side at predetermined intervals to prevent the color filter substrates from touching each other have been used. shaped storage container. [0004] Patent Document 1: JP-A-2002-264992 [0005] However, recently, it is required to manufa...
