Electro-optic assembly having an antireflective electrode stack with covert conduction wells

An electro-optic assembly, comprising:

• a front substrate having a first surface and a second surface opposite the first surface;
• a second substrate having a third surface and a fourth surface opposite the third surface, the second and third surfaces facing each other to define a gap;
• a first antireflective electrode stack coupled to the second surface;
• a second antireflective electrode stack coupled to the third surface;
• an electro-optic medium located between the first antireflective electrode stack and the second antireflective electrode stack;
• and
• each of the first and second antireflective electrode stacks comprising:
• a conductive layer formed of a transparent conductive oxide;
• an overcoat layer in contact with the electro-optic medium and formed of a substantially transparent conductive material;
• an insulating layer between the conductive layer and the overcoat layer;
• and
• a plurality of conduction wells at least partially containing the electro-optic medium and extending through the insulating layer.
