Abstract:
1. 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 having a thickness sufficient to scatter light transmitted through said first substrate and reflect the light toward said first substrate; a transparent first electrode disposed on said first substrate; and a second electrode for moving said charged particles between said first and second electrodes by applying a voltage between said first and second electrodes, wherein both of a position of said charged particles after being moved to said first electrode and a position of said charged particles after being moved to said second electrode are substantially apart from a surface of said reflection layer, wherein said apparatus further comprises a partition wall for partitioning the spacing into a plurality of sections, and wherein each of said plurality of sections defines a pixel, a voltage is applied to said first electrode through a switching device at each pixel independently of other pixels, and an electric potential common to each pixel is applied to said second electrode, and wherein the switching device is disposed between said partition wall and said second substrate.
