Polarizerless Nanomaterial Doped Guest-Host LCD Exhibiting High Luminance and Good Legibility

Abstract

A polarizerless reflective guest-host (GH) LCD, which exhibits high luminance and good legibility, has been fabricated by using NLC with a negative Δε that is doped with nanomaterial molecules, fulleren C₆₀, and dichroic dye molecules, where the NLCs are homeotroptically aligned without rubbing. It is considered that the doped C₆₀ molecules may play a role in reducing the order parameter of the host NLC, and in turn, the contrast ratio is enhanced because the transmittance of the field induced black state in our GH-LCD is lower than that in conventional GH-LCD without C₆₀.
