The electric‐field‐induced liquid‐crystal (LC) cholesteric‐to‐nematic (C‐N) phase transformation and its relaxation (N‐C) are examined using the anisotropic color absorption properties of a dichroic dye dopant. A tristability is observed. The stable memory associated with the tristability has potential application to display devices. The N‐C relaxation characteristics are found to be related to the ratio of LC‐film thickness to pitch length (d/p).
