Paper Abstract

Light valve using suspended particles was invented first by Edwin H. Land. But it could not be made to large area because it was a liquid cell containing a suspension of the particles between both transparent conductive layers. For several years, so many trials have been to make a large size of light valve. Recently we could make the light valve of large size which is film type by phase separation and/or emulsification methods. In this paper, we are introducing the light valve film made by HGI.
