Short Communication: Spectrum of Voltage Controllable Color Formation with Nematic Liquid Crystals

A number of reports on color display devices with nematic liquid crystals have been published1–6. In a previous paper we have reported on the optimum conditions for voltage controllable color formation (VCCF) with a panel operated in the tunable birefringence mode in which a nematic liquid crystal with a positive dielectric anisotropy (Δ∈ > 0) was utilized. We also reported on its spectral width6, where the effect of absorption anisotropy was neglected. This communication describes the whole transmission spectrum by taking absorption anisotropy into account.
