Patent ID: 8687257

Claim:
An optical device, comprising: a first substrate and a second substrate placed opposite each other; a partition sandwiched between the first substrate and the second substrate; a first electrode provided on one side of the first substrate, at least a part of the first electrode overlapping with a region enclosed by the partition; a second electrode and a third electrode provided on one side of the second substrate and which are respectively placed opposite the first electrode across the region enclosed by the partition; a smoothing layer provided on one side of the second substrate and which covers the second electrode and the third electrode; a light shielding layer disposed on at least one of the first substrate and the second substrate, the light shielding layer being disposed at least in a region where the first electrode and the third electrode overlap; and a first fluid and a second fluid, which are immiscible, disposed in the region enclosed by the partition, wherein the first fluid posseses polarity or conductivity, and the second fluid comprises liquid crystal material.
