Abstract
The present invention provides a liquid crystal composition, containing: one kind or two or more kinds of a first monomer having a first mesogenic skeleton, at least one polymerizable group represented by the general formula (PG1) linked to the first mesogenic skeleton, and at least one polar group linked to the mesogenic skeleton or the polymerizable group; and one kind or two or more kinds of a second monomer having a second mesogenic skeleton and a polymerizable group represented by the general formula (PG2) linked to the second mesogenic skeleton, and having a chemical structure different from that of the first monomer, in an amount of more than 0.4% by mass, which is excellent in vertical alignment, burn-in characteristics (change with time of pretilt angle), and compatibility, and provides a liquid crystal display element using the liquid crystal composition.
