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).
