A cholesteric liquid crystal took a transparent or opaque state at 29 V depending on whether the voltage was decreasing or increasing. The transmittance difference of these bistable states, however, decreased in a pixel of 2 mm square that corresponded to the intersection of two orthogonal electrodes (2 mm width) on the opposing glass plates. The transmittance difference increased when the pixels were enclosed by a silicone film for eliminating molecular interaction between neighboring pixels.
