Claim:
1. A window assembly comprising: an outer window panel; an inner window panel; a conductive layer disposed at an inner surface of said inner window panel; a spacer element disposed between said inner and outer window panels to establish an interpane cavity between said inner and outer window panels; a roller shade disposed within said interpane cavity, wherein said roller shade has an end fixedly attached at an anchor stop along a perimeter portion of said spacer element; a dielectric layer disposed between said roller shade and said conductive layer; wherein said roller shade is electrically deployable to coil and uncoil between a coiled light transmitting condition, where said roller shade is coiled along said perimeter portion of said spacer element and functions to substantially allow light transmission through said window assembly, and an at least partially uncoiled light attenuating condition, where said roller shade is uncoiled to at least partially cover a surface of said inner window panel and functions to at least partially attenuate light transmission through said window assembly; wherein said roller shade is electrically operable via applying a voltage at said transparent conductive layer and at said anchor stop to uncoil said roller shade from said coiled light transmitting condition to said at least partially uncoiled light attenuating condition, and wherein an electrical connection is made between said roller shade and a power source to provide electrical power to said roller shade; wherein said roller shade comprises a laminate material comprising a shade dielectric layer, a conductive layer and an opaque layer, and wherein said conductive layer is disposed at a lower portion of said shade dielectric layer and said opaque layer is disposed at a lower surface of said conductive layer; and wherein said anchor stop comprises a curved receiving portion that is curved to generally correspond with the curvature of said roller shade when it is coiled at said curved receiving portion of said anchor stop.
