Abstract: The light-controlling device includes a first substrate, a second substrate and a partition wall separating the first and second substrates to define a cell. A light-adjustment medium containing a plurality of charged particles is disposed between the first and second substrates. One of the first electrode on the first substrate and the second electrode on the second substrate covers lesser area of the light-controlling device than the other electrode. The electrode covering lesser area of the light-controlling device may have grooved surface to increase the surface area without increasing the overall area of the light-controlling device covered by the electrode. Particle guidance member can be used to create a reservoir for holding increased amount of charged particles on the electrode covering lesser area of the light-controlling device.
