摘要：PROBLEM TO BE SOLVED: To provide a liquid crystal cured film that has little generation of defects and excellent transparency and facilitates transfer.SOLUTION: The liquid crystal cured film is formed from a polymerizable liquid crystal compound having an ethylenically unsaturated bond and an aromatic ring, and satisfies expression (Y):0.95>P1/P2>0.60. In the expression, P1 represents a P value on one of the surfaces perpendicular to a thickness direction of the liquid crystal cured film; P2 represents a P value on the other surface; and P is defined by P=I(1)/I(2), where I(1) represents a peak intensity derived from in-plane deformation vibration of the ethylenically unsaturated bond obtained by the measurement of an infrared total reflection absorption spectrum and I(2) represents a peak intensity derived from stretching vibration of an unsaturated bond in the aromatic ring obtained by the measurement of an infrared total reflection absorption spectrum.
