Abstract

A rear-view mirror installed in a transport vehicle is provided. The rear-view mirror includes a first substrate, a second substrate, an electrochromic material layer, a light-transmitting electrode, a reflective layer, and a transparent conductive layer. The second substrate is opposite to the first substrate. The electrochromic material layer is disposed between the first substrate and the second substrate. The light-transmitting electrode is disposed between the first substrate and the electrochromic material layer. The electrochromic material layer is disposed between the first substrate and the reflective layer. The transparent conductive layer is disposed between the electrochromic material layer and the reflective layer. In addition, a driving auxiliary apparatus is also provided.

Claims
