This is because when the touch panel and the substrate are in close contact with each other, there is distortion or the like on either surface, which causes a phenomenon of coloring or light and shade due to the interference of reflected light. Problems such as poor visibility, input errors, and double eye strain have arisen, and improvements have been demanded.

On the other hand, it may be about 0.5 to 30% by weight. If the amount of fine powder used is 0.5% by weight or less, the effect of preventing Newton's rings is not sufficient, and if the amount used is 30% by weight or more, the transparency of the touch panel may be affected. Such a binder is usually used by dissolving it in a solvent, but the amount of the solvent used may be appropriate depending on the coating method and is not particularly limited.
