ABSTRACT:
A liquid crystalline composition comprises at least one kind of biphenyl type liquid crystal materials having the positive dielectric anisotropy and at least one kind of other liquid crystal materials. The novel liquid crystalline composition of the present invention possesses extended ranges of the nematic mesomorphic temperature which are significantly larger than those of the individual liquid crystal material of the composition and are stable at a room temperature.
