ABSTRACT:
An apparatus includes a transparent film substrate and a second substrate which are disposed opposite to each other with a spacing therebetween, a plurality of charged particles which are disposed in the spacing, a reflection layer having a thickness sufficient to scatter light transmitted through the first substrate and reflect the light toward the first substrate, a transparent first electrode disposed on the first substrate, and a second electrode for moving the charged particles between the first and second electrodes by applying a voltage between the first and second electrodes. Both of a position of the charged particles after being moved to the first electrode and a position of the charged particles after being moved to the second electrode are substantially apart from a surface of the reflection layer.
