Gray-scale in polymer-stabilized antiferroelectric liquid crystal displays
View through CrossRef
We have investigated an antiferroelectric liquid crystal which is stabilized by a polymer network. The latter is formed by in situ photopolymerization of a mesogenic diacrylate. The pure liquid crystalline monomer shows the well-known tristable electro-optic switching due to a field induced transition from the antiferroelectric to the ferroelectric state. The change of the optical transmittance due to this transition becomes more continuous if a polymer network is present. Thus, different gray shades can be easily achieved in polymer-stabilized antiferroelectric liquid crystals.
