Thin wire bus bar

An electro-optic device comprising:

• a first substrate having a rear surface and a second substrate having a front surface opposed to the rear surface of the first surface;
• a cavity defined between the rear surface of the first substrate and the opposed front surface of the second substrate;
• an electrically conductive coating disposed on at least one of the rear surface of the first substrate and the front surface of the second substrate;
• a first metal strip having a first surface, a second surface, a thickness measured between the first surface and the second surface, and a width, extending at least partially around a circumference of the rear surface of the first substrate;
• and
• a sealing member bonding first substrate and second substrate together in a spaced apart relationship;
• wherein the sealing member at least partially covers at least a portion of the second surface of the first metal strip.
