重合性液晶組成物および位相差板
Document Type and Number:
Japanese Patent JP7255975
Kind Code:
B2
Abstract:
A polymerizable liquid crystal composition containing two polymerizable liquid crystal compounds (A) and (B) is provided. A polymer of compound (A) exhibits a reverse wavelength dispersion property and the phase difference value [R(A,3000,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 3000 mJ/cm2 varies in a positive sense relative to the phase difference value [R(A,500,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 500 mJ/cm2. A polymer of compound (B) exhibits a reverse wavelength dispersion property and the phase difference value [R(B,3000,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 3000 mJ/cm2 varies in a negative sense relative to the phase difference value [R(B,500,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 500 mJ/cm2.
