| titleOfInvention | Method for Producing a Liquid Crystal Material Having a Broadened Light Reflection Band |
| abstract | The invention relates to a method of producing a liquid crystal material that can be addressed by an electric field. The inventive method is characterised in that it comprises the following steps consisting in: forming a liquid crystal mixture having a helical structure comprising a first non-photoreactive liquid crystal and a second photoreactive liquid crystal, said first liquid crystal comprising first chiral liquid crystal molecules and having a positive dielectric anisotropy and said second liquid crystal being in a concentration of less than or equal to 5% of the mixture; applying a first treatment to the liquid crystal mixture, said first treatment being performed at a constant temperature and modifying a pitch of the helix of the mixture; and applying a second treatment to the mixture, such that the second liquid crystal forms a polymer network, said second treatment being performed during all or part of the first treatment such that the liquid crystal material retains a memory of the modifications to the pitch of the helix. The invention also relates to a liquid crystal device comprising a liquid crystal material that is produced using the inventive method. |
