  • Publication number: 20150085236
    Abstract: 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.

  • Patent number: 8962104
    Abstract: The present invention provides a liquid crystal display panel that suppresses the temperature dependence of transmittance-gradation characteristics and thus overcomes problems in which significant changes in transmittance-gradation characteristics are caused by the effects of environmental temperature and a light source to lead to the degradation of display performance, and a liquid crystal display device including the liquid crystal display panel. The liquid crystal display panel of the present invention includes a liquid crystal medium containing a plurality of liquid crystal compounds each having a negative dielectric constant anisotropy, the liquid crystal medium being held between a first substrate and a second substrate that are located opposite each other, and a side of each of the substrates in contact with the liquid crystal medium having vertical alignment properties for the liquid crystal compounds.
