The electrooptic characteristics of cholesteric-nematic mixtures were studied in relation to surface alignment, layer thickness (<i>d</i>) and helical pitch (<i>p</i>). It was made clear that their characteristics could be consistently understood by taking the ratio (<i>d</i>/<i>p</i>) of layer thickness to helical pitch into consideration, and the optimum value of <i>d</i>/<i>p</i> for display devices was about 0.7 for the parallel-aligned cell (parallel cell) and about 0.5 for the vertical-aligned cell (vertical cell).
