A novel thermal-addressing liquid crystal device (TALCD) was proposed for the [polymer network/liquid crystals/chiral dopant) composite system with a smectic-A (SA) ↔ chiral nematic (N) phase transition. In the case of this novel TALCD, in an opposite fashion to conventional TALCDs which show light-scattering characters on a transparent background, transparent characters were stored on a light-scattering background. This novel TALCD showed a very fast speed for memory switching, an enough contrast and an endurable memory effect.
