发明名称 LIQUID CRYSTAL CURED LAYER
摘要 <p>A liquid crystal cured film is provided wherein a transfer is easy, a defect occurrence is low, and a liquid crystal cured film having an excellent transparency is provided. [Means for solving problem] A liquid crystal cured film formed from a polymerizable compound having an ethylenically unsaturated bond and an aromatic ring and satisfying the formula (Y). 0.95 > P1/P2 > 0.60 (Y). [P1 means a P value in one surface of surfaces perpendicular to the thickness direction of the liquid crystal cured film. P2 means a P value in other surface. P = I (1 )/I (2). I (1) means a peak intensity originated from an in-plane deformation vibration of an ethylenically unsaturated bond by measuring an infrared total reflection absorption spectrum. I(2) means a peak intensity originated from a stretching vibration of an aromatic ring by measuring an infrared total reflection absorption spectrum.]</p>
