摘要:
The present invention provides a polymerizable liquid crystal composition containing polymerizable liquid crystal compounds and a photoinitiator, wherein the photoinitiator has a light absorption band in a wavelength range of 280 to 400 nm; and at least one of the polymerizable liquid crystal compounds has a light absorption band in a wavelength range of 320 to 400 nm or a light-absorbing agent having a light absorption band in a wavelength range of 280 to 400 nm is contained. Thus, there is provided a material that can be cured in the air without replacing the atmosphere with an inert gas during irradiation with ultraviolet rays and that can achieve the characteristics required for a biaxial film, such as a sufficiently large front phase difference.
