1. A switchable laminated glazing, comprising:
a first stack of components having:
an exterior glass layer having inner and outer surfaces;
an intermediate glass layer having inner and outer surfaces; and
at least one plastic bonding layer located between inner surfaces of said exterior and intermediate glass layers; and
a second stack of components having:
an interior glass layer having inner and outer surfaces;
a first cured liquid optically clear adhesive; and
a liquid crystal layer;
wherein the second stack of components is disposed on and bonded to the first stack of components by said first cured liquid optically clear adhesive, such that the liquid crystal layer is sandwiched between the outer surface of the intermediate glass layer and the inner surface of the interior glass layers with the first cured liquid optically clear adhesive;
wherein the first cured liquid optically clear adhesive and the liquid crystal layer are located within a sealed space, said sealed space defined by and sealed exclusively by the intermediate glass layer, the interior glass layer, and a perimeter seal, and wherein the perimeter seal is located between and directly contacts the intermediate and interior glass layers;
wherein the liquid crystal layer comprises liquid crystals, two confronting polymeric substrates to encapsulate said liquid crystal layer, an edge seal and spacers;
wherein the laminated glazing is a vehicle roof or vehicle side window; and
wherein the switchable laminate glazing is curved.
