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.
Claims4
An apparatus, comprising:
- 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 disposed on said second substrate, said reflection layer having a thickness sufficient to scatter light transmitted through said first substrate and reflect the light toward said first substrate;
- and
- a first electrode and a second electrode for dispersing said charged particles in a broader area and collecting said charged particles in a narrower area by applying a voltage between said first and second electrodes,
- wherein said reflection layer is formed with a material comprising light-reflective particles dispersed in a transparent insulating resin.
