摘要:
To provide a liquid crystalline composition, which can be obtained by mixing a plurality of liquid crystalline compositions each of which can exhibit different liquid crystal phases from one another, being capable of exhibiting a biaxial liquid crystal phase, a liquid crystalline composition contains a liquid crystalline composition R which exhibits a liquid crystal phase having a positive birefringence; and a liquid crystalline composition D which exhibits a liquid crystal phase having a negative birefringence, in which the liquid crystalline composition R comprises a compound having a rectangular plate-like shape.
