Electrooptical liquid crystal system |
| abstract |
The invention relates to an electrooptical liquid crystal system which contains a dual frequency liquid crystal mixture and a further optically transparent polymeric medium between two electrode layers which optionally may be attached to substrates; in which the ordinary refractive index of the liquid crystal mixture essentially agrees with the refractive index of the polymeric medium nm and/or in which the quotient of the mass of the liquid crystal mixture and of the mass of the polymeric medium is 1.5 or more; which has reduced transmission in the on-state compared to the off-state; and which is obtained by polymerization of a composition containing the dual frequency liquid crystal mixture and a precursor of the polymeric medium, characterized in that an electrical field is applied during the curing process which exhibits a frequency below the cross-over frequency of the dual frequency liquid crystal mixture so that the molecules of the dual frequency liquid crystal mixture are aligned essentially into the direction of the electrical field. |
