1. An electrochromic device, comprising:
a first substrate and a second substrate provided opposite to each other;
a first transparent conductive layer and a second conductive layer provided between the first substrate and the second substrate;
an electrochromic layer provided between the first transparent conductive layer and the second conductive layer;
a bottom printed layer provided on a surface of the second substrate away from the second conductive layer; and
a pattern layer;
wherein an orthographic projection of the pattern layer on the first substrate covers at most a part of a surface of the first substrate, and a color of the electrochromic device varies as a voltage between the first transparent conductive layer and the second conductive layer changes.
