Abstract

A scattering liquid crystal (LC) film comprises two ITO coated plastic (or glass) substrates in between which is a polymeric material containing micro droplets of nematic LC. The scattering efficiency of the film is voltage controllable. The packaging of the LC film for an optical attenuator is studied.
