LIQUID CRYSTAL DISPLAY ELEMENT

WIPO Patent Application WO/2020/137574

A1

Provided is a liquid crystal display element that is excellent in terms of its liquid crystal orientation, orientation stability, high voltage holding ratio, and voltage holding ratio stability.　The liquid crystal display element according to the present invention is characterised by comprising two substrates and a liquid crystal layer provided between said two substrates, the liquid crystal layer including liquid crystal molecules and a polymer of polymerisable monomers, the residual amount of the polymerisable monomers in the liquid crystal layer being 200 ppm or less. Moreover, the residual amount of the polymerisable monomers in the liquid crystal layer is preferably 10 ppm or more. In addition, the polymerisable monomers preferably include a polymerisable monomer A having an adsorbing group.
