— A mixture with intermediate biaxial (ferrielectric) smectic phases existing in a broad temperature range has been developed. At any temperature within this range, as well as in the antiferroelectric phase range, several birefringence color states can be switched stepwise by application of an electric field, and therefore a LC cell placed between crossed polarizers can display form several colors without the use of color filters. A very small time switching between color states (about 10 μsec) can be a basis for this new mode in display technology because several full‐color optical states can be realized in the same material (or in the mixture of materials). These possibilities were investigated both theoretically and experimentally.
