ABSTRACT:
A liquid crystal composition is provided and includes: at least one kind of liquid crystal R exhibiting a liquid crystal phase having a positive birefringence property; and at least one kind of liquid crystal D exhibiting a liquid crystal phase having a negative birefringence property. The characteristic birefringence Δn (λ) at wavelength λ of the liquid crystal phase exhibited by the liquid crystal R satisfies the equation (II): Δn (450 nm)/Δn (550 nm)<1.0.
