Therefore, it is best to be on the grounding layer 6 A cross-linking treatment or a crystallization treatment is performed to improve the waterproof performance and heat resistance. In particular, after the film of the ground layer 6 is formed by adding a cross-linking agent to a solvent of a hydrophilic resin, the cross-linking reaction occurs by irradiation or heating. In addition, the ground layer 6 without cross-linking agent is crystallized through heat treatment (for example, using polyvinyl alcohol (PVA) as a hydrophilic resin, whereby p VA is converted to PVA that changes its nature). When the cross-linking treatment is compared with During the crystallization treatment, the cross-linking treatment is better than the crystallization treatment because there is no bad influence due to heating the transparent substrate 1 and the workability is also good. Hereinafter, examples of the crosslinking reaction will be described. In practical applications where the examples are carried out, it is possible to use arbitrary examples appropriately between these crosslinking reactions.
