A DAP (Deformation of Aligned phase of Nematic) type liquid crystal display is enabled with a voltage having a periodically variable effective value. The displaying color of the DAP type liquid crystal display is changed by cyclic variation in the effective value of the applied voltage.

DAP Type liquid crystal display with means for obscuring viewing angle

A liquid crystal composition comprising at least one of substituted bipheny-type and substituted terphenyl-type liquid crystal substances and at least one of substituted phenyl benzoate-type and substituted phenyl thiobenzoate-type liquid crystal substances, the composition further containing at least one substituted cyclohexyl benzene-type liquid crystal substance when desired. The composition has the characteristics of being wide in mesomorphic range, low in threshold voltage, satisfactory in orientation, quick-responsive, highly reliable and capable of exhibiting fully satisfactory performance when driven by a single compact power cell coupled directly thereto. The composition is useful for field effect mode liquid crystal display devices.

Liquid crystal compositions

Liquid crystal material suitable for use in small display devices and consisting of one or more biphenyl or terphenyl compounds and one or more ester compounds, whereby low threshold voltage characteristics of one type of compound are complemented by the low viscosity and good response characteristics of the other type of compound, and liquid crystal material having good overall characteristics is achieved.
