摘要： The present invention relates to a liquid crystal display that incorporates a particular liquid crystal composition and a sealant in which a cured form of a particular curable resin composition is used. The present invention provides a liquid crystal display that prevents reduced voltage holding ratio (VHR) and increased ionic density (ID) in the liquid crystal layer and solves the problems of display defects such as voids, alignment irregularities, and image-sticking. Liquid crystal displays according to the present invention, featuring the ability to prevent reduced voltage holding ratio (VHR) in the liquid crystal layer and reduce the occurrence of display defects such as alignment irregularities and image-sticking, are useful particularly to liquid crystal displays in the IPS and FFS modes for active matrix drive and applicable to liquid crystal displays of equipment such as liquid crystal TVs, monitors, mobile phones, and smartphones.

摘要： The present invention relates to a liquid crystal display device including a particular liquid crystal composition and a cured product of a particular curable resin composition serving as a sealant. The present invention provides a liquid crystal display device that does not suffer from a decrease in the voltage holding ratio (VHR) or increase in the ion density (ID) of the liquid crystal layer or the problem of display defects such as white spots, alignment unevenness, and image-sticking. Since the liquid crystal display device according to the present invention does not suffer from a decrease in the voltage holding ratio (VHR) of the liquid crystal layer or display defects such as alignment unevenness and image-sticking, the liquid crystal display device is particularly useful as an active-matrix-driven liquid crystal display device such as a VA, PSVA, IPS, or FFS liquid crystal display device and can be used as a liquid crystal display device for products such as liquid crystal display televisions, monitors, cell phones, and smartphones.

摘要： The present invention provides a polymerizable liquid crystal composition containing polymerizable liquid crystal compounds and a photoinitiator, wherein the photoinitiator has a light absorption band in a wavelength range of 280 to 400 nm; and at least one of the polymerizable liquid crystal compounds has a light absorption band in a wavelength range of 320 to 400 nm or a light-absorbing agent having a light absorption band in a wavelength range of 280 to 400 nm is contained. Thus, there is provided a material that can be cured in the air without replacing the atmosphere with an inert gas during irradiation with ultraviolet rays and that can achieve the characteristics required for a biaxial film, such as a sufficiently large front phase difference.
