IMPROVED ACTIVE LIGHT CONTROL DEVICE ABSTRACT OF DISCLOSURE A light control device comprises a plurality of minute particles, having dipolar and light control charac- teristics, which are supported in an elastic solid matrix. The particles have a length to width ratio greater than two and are supported in a common orientation across the elastomeric matrix to block (or transmit) incident light. Under application of an electric field across the layer the particles reorient to provide a reverse light control effect. Upon removal of the field the particles quickly return to their original orientation. Image display em- bodiments utilizing a photoconductor or other imagewise field providing structures are disclosed. -1-
