摘要： A laminate including a vertically oriented liquid crystal cured film and a horizontally oriented phase difference film is provided. The vertically oriented liquid crystal cured film is a cured product of a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound and a dichroic coloring matter. The composition includes, as the dichroic coloring matter, at least one type of dichroic coloring matter having maximum absorption between a wavelength of 400 nm and a wavelength of 750 nm. The vertically oriented liquid crystal cured film is a cured product of the polymerizable liquid crystal composition that is cured in a state in which the polymerizable liquid crystal compound is oriented in a vertical direction with respect to a flat plane of the liquid crystal cured film, and satisfies the following formula (1) and the following formula (2): 0.001≤AxC≤0.3 (1); AxC(z=60)/AxC>2 (2).

摘要： 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.
