摘要： An optical device includes: a sealed container having edge walls facing each other in a thickness direction of the container and a side wall connecting both of the edge walls; a first liquid with polarity or electrical conductivity and sealed within the container; a second liquid that is sealed within the container and does not mixed with the first liquid; and a voltage applying unit for applying a voltage across the first liquid. The first and second liquid have equal specific gravity, and transmissivity of the first liquid is lower than the transmissivity of the second liquid. An interface between the first liquid and the second liquid changes shape in response to a voltage applied by the voltage applying unit. The first liquid is formed so as to have equal specific gravity to the second liquid by mixing three or more kinds of liquids each having a different specific gravity.

摘要： A power-saving, highly-reversible optical device is provided. The transmittance through the device is well controlled within a visible ray range. The device has good spectral characteristics while shielded from light, and the electrodes in the device are prevented from being in overpotential condition. The device has a long life, and is protected from being discolored and deteriorated in cycle use. Also, an electrolytic solution to be used in the device is provided. The optical device comprises a solution as so put between working electrodes and a counter electrode that driving control of these electrodes brings about deposition or dissolution of silver. In this, the solution is prepared by dissolving a silver salt in a solvent, to which are added a supporting salt of an alkali metal halide such as LiBr or the like, and an alkanolamine, and optionally coumarin and a mercaptoalkylimidazole.
