FIELD: physics. ^ SUBSTANCE: element has two parallel transparent plates with transparent electrodes on inner sides between which there is a film of a capsular polymer of cholesteric liquid crystal, and the cholesteric liquid crystal used is a mixture of an ionic surfactant and a cholesteric liquid crystal with arbitrary value of dielectric anisotropy. On the outer sides of the transparent plates there are crossed polarisers. ^ EFFECT: obtaining multistable optical states of an electrooptic element based on capsular polymer of cholesteric liquid crystal: light-absorbing state, partially transparent state and intermediate states, which can be realised at any values of dielectric anisotropy of the cholesteric liquid crystals used. ^ 2 dwg, 1 ex |
