In Comparative Examples 3, 5, 7, and 8, the pen sliding durability test is excellent, but other characteristics are inferior. Comparative Example 3 is not suitable for use because the total light transmittance is lower than a practical level. Comparative Example 5 is not suitable for use because the surface resistance is higher than a practical level. In Comparative Examples 7 and 8, the flatness of the touch panel is not sufficient.
