| 摘要 |
The present invention provides a liquid crystal display device that is less prone to display defects and a decrease in the voltage holding ratio regardless of the presence or absence of an alignment film. The liquid crystal display device includes: a pair of substrates; a liquid crystal layer containing a liquid crystal material between the substrates; and a polymer layer for controlling alignment of liquid crystal molecules on a surface of at least one of the substrates, the substrates being substantially free of an alignment film in outermost surfaces thereof, the polymer layer being formed by polymerization of at least two kinds of radical polymerizable monomers in the liquid crystal layer, at least one of the radical polymerizable monomers being a compound having a structure that creates a ketyl radical as a result of hydrogen abstraction induced by light radiation. |
