LIQUID CRYSTAL CURED LAYER

摘要

Provided is a liquid crystal cured layer wherein a transferring is easily performed, resulting in reducing the occurrence of defects and exhibiting excellent transparency. A liquid crystal cured layer formed from a polymerizable liquid crystal compound having an ethylenically unsaturated bond and an aromatic ring and satisfying a formula (Y). 0.95>P1/P2>0.60 (Y) [P1: P value for one of surfaces vertical to a thickness direction of the liquid crystal cured layer, P2: P value for the other of surfaces vertical to a thickness direction of the liquid crystal cured layer, P=I(1)/I(2), I(1): Peak intensity from in-plane deformation vibration of the ethylenically unsaturated bond measured by attenuated total reflection IR spectroscopy, and I(2): Peak intensity from stretching vibration of an unsaturated bond of the aromatic ring measured by attenuated total reflection IR spectroscopy]

1. A liquid crystal cured layer formed from a polymerizable liquid crystal compound having an ethylenically unsaturated bond and an aromatic ring, the layer satisfying a formula (Y),
0.95>P1/P2>0.60  (Y) wherein P1 is a value of P taken in one of two surfaces of the liquid crystal cured layer perpendicular to the thickness direction of the layer, P2 is a value of P taken in the other surfaces, wherein P is defined by
P=I(1)/I(2) wherein I(1) is the intensity of a peak derived from in-plane deformation vibration of the ethylenically unsaturated bond measured by attenuated total reflection IR spectroscopy, and I(2) is the intensity of a peak derived from stretching vibration of an unsaturated bond of the aromatic ring measured by attenuated total reflection IR spectroscopy.
