Effect of monoacrylates on electro-optical properties of light-scattering LCDs

Electro-optical properties for light scattering liquid crystal displays (LCDs) prepared by using liquid crystalline monoacrylate, phenoxyl monoacrylate and alkyl monoacrylate as a component of monomer shave been investigated. The properties strongly depend on the chemical structure of monoacrylate. The liquid crystalline monoacrylate has effects to reduce the driving voltage and the hysteresis. The effect of the terminal group and the number of core-ring in the liquid crystalline monoacrylate on the driving voltage and the hysteresis is discussed. A memory phenomenon observed at low temperature is influenced by the chemical structure and the content of monoacrylate. The temperature dependence of the driving voltage and the hysteresis for the light scattering LCDs is discussed. Based on these result, a light scattering LCD with low driving voltage, small hysteresis and small temperature dependence has been achieved.
