— We have carried out systematic investigations on a non‐polar dichroic‐dye‐doped bistable polymer‐stabilized cholesteric‐texture (PSCT) normal‐mode light modulator. The addition of a small amount of dichroic dye (∼1.0 wt.%) helps considerably to reduce the transmittance in the OFF state and therefore gives rise to an overall improvement in contrast ratio. Furthermore, collection‐angle dependence of the contrast ratio is reduced by the addition of the dichroic dye.
