Electrochromic mirror

摘要

A conventional electrochromic mirror comprises an ion conductive layer provided between a transparent electrically conductive substrate and a reflective electrically conductive substrate and containing spacers. The spacers can be perceived when the mirror was viewed. According to the present invention, the difference in refraction index between the spacers and the ion conductive layer is ±0.03 or less. Therefore, the electrochromic mirror having spacers in the ion conductive layer which are hardly perceived can be provided.
