Electrically controllable device with variable scatterability by liquid crystal

摘要

The present invention is a first electrode (2); Electroactive layer 3; It relates to a device 100 having a second electrode 2 ', and having variable scattering properties by liquid crystal. This is the first transparent polymeric barrier layer 4 of thickness T ₁ between the first electrode and the electroactive layer and the optional second transparent polymeric barrier layer of thickness T ₂ between the second electrode and the electroactive layer. , Wherein T ₁ is not 0 and is at least 1 μm, and T1 + T2 is up to 40 μm. The first polymeric barrier layer holds the first electrode or the first electrode is on the first dielectric substrate 1. An optional second polymeric barrier layer holds the second electrode or the second electrode is on the second dielectric substrate 1 '.
