摘要:
A container suitable for storing a polymerizable liquid crystal composition liquid intended for providing, after temporal or long-term storage, a liquid crystal cured layer that is homogeneous and hardly causes alignment defects is described. A container containing a polymerizable liquid crystal composition liquid includes a gas phase part and a liquid phase part containing a polymerizable liquid crystal composition liquid. The polymerizable liquid crystal composition liquid contains a polymerizable liquid crystal compound; at least one solvent selected from a ketone solvent, an amide solvent, an ester solvent, and an ether solvent; a photopolymerization initiator, and a polymerization inhibitor in an amount of 0.1% by mass or more and 2% by mass or less based on the polymerizable liquid crystal compound. The gas phase part has an oxygen concentration of 0.05% by volume or more and 20.8% by volume or less.
