| 摘要 |
Disclosed is an optical film comprising an oriented polymerizable liquid crystal compound, wherein it holds that the absorbance A, measured using a solution (a), of the polymerizable liquid crystal compound at 400nm is 0.1 or less, and that the degree of orientational order S0, measured using the solution (a), of the optical film at the maximum absorption wavelength of the polymerizable liquid crystal compound is -0.50 < S0 < -0.15. Solution (a): a solution in which the polymerizable liquid crystal compound is dissolved in chloroform so as to attain a concentration of 10-4 mol/l. |
