Method for controlling optical transmissions, device for controlling optical transmissions, and method for manufacturing same

A device for adjusting light transmission, comprising:

• charged particles composed of a light blocking material;
• a first solvent in which the particles are dispersed;
• and
• a second solvent not being mixed with the first solvent,
• wherein the particles are mixed with the first solvent but are not mixed with the second solvent, and
• wherein light transmittance is adjusted by adjusting an electric field applied to the particles to move the particles and moving the first solvent together with the particles using a difference in movement resistance at an interface between the particles and the first solvent and that at an interface between the first solvent and the second solvent to control a blocking area of the first solvent with respect to a light incident surface.
