Claim:
1. A switchable window comprising: a first substrate and a second substrate for the window; a liquid crystal inclusive layer disposed between at least the first substrate and the second substrate; a low-E coating provided between at least the liquid crystal inclusive layer and the first substrate; wherein the low-E coating includes at least one infrared (IR) reflecting layer comprising silver and first and second dielectric layers; a conductive coating provided between at least the liquid crystal inclusive layer and the second substrate, so that voltage is to be applied to the liquid crystal inclusive layer via the low-E coating and the conductive coating which are on opposite sides of the liquid crystal inclusive layer; and wherein, by adjusting voltage applied to at least part of the liquid crystal inclusive layer via the low-E coating and the conductive coating, the window is selectively switchable between at least first and second states, where the window has a higher visible light transmission in the first state than in the second state.
