Claim 10:
11. A window comprising an optical device which is operable in and electrically switchable between at least two optical states having a layer structure comprising in this order
a first transparent substrate,
a first patterned electrode,
a switching layer comprising a medium configured to modulate light in response to an applied voltage,
a second patterned electrode, and
a second transparent substrate,
wherein the first and second patterned electrodes are patterned such that at least one electrically insulated segment having a predetermined shape is formed on each of the first and second transparent substrates,
wherein the first and second patterned electrodes are aligned and the electrically insulated segments are arranged in a manner such that an image having at least one closed feature is portrayed by the optical device in one of the optical states,
wherein the first transparent substrate and the second transparent substrate of the optical device are arranged such that a region of the first transparent substrate does not overlap with the second transparent substrate, and a region of the second transparent substrate does not overlap with the first transparent substrate, and
wherein the optical device has a size greater than 1 m2.
