摘要： The present invention relates to a liquid crystal display device including a specific liquid crystal composition and a sealant containing the cured product of a specific curable resin composition. The present invention provides a liquid crystal display device which prevents a decrease in the voltage holding ratio (VHR) of the liquid crystal layer and an increase in ion density (ID) and which enables elimination of problematic defective display such as voids, uneven alignment, and screen burn-in. Since the liquid crystal display device of the present invention prevents a decrease in the voltage holding ratio (VHR) of the liquid crystal layer and enables a reduction in defective display such as uneven alignment and screen burn-in, it is particularly useful for active-matrix liquid crystal display devices of an IPS mode and FFS mode and can be applied to liquid crystal display apparatuses such as liquid crystal TVs, monitors, mobile phones, and smartphones.

摘要： As a mobile display device, a translucent liquid crystal panel is a highly user-friendly display device capable of obtaining a clear image both in a dark place and a light place. However, it is expected to obtain a light-weight and robust display device of lower power consumption , i.e., having the advantages of the transparent type and reflection type liquid crystal panel. A liquid crystal panel having a back surface light emission light source includes: a liquid crystal element formed on a first basic body and sandwiching a liquid crystal element between a transparent first electrode and a transparent second electrode which are arranged to oppose each other; and a back surface light emission light source of the liquid crystal element formed on a second basic body and sandwiching a thin film planar light emitting element between an optically opaque third electrode and a transparent fourth electrode which are arranged to oppose each other. The third electrode is a reflection film arranged on the second basic body side and reflecting external light coming through the liquid crystal layer so as to introduce it into the liquid crystal layer. The fourth electrode is arranged to oppose to the second electrode. The insulation film sandwiched by the fourth electrode and the second electrode is a film formed continuously on the fourth electrode.

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： A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 µm to 200 µm, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/°C or , less. Furthermore, it more preferably gives a variation of ±5 % or less in mechanical and optical properties to a thermal history at 200 °C.

摘要： A conventional liquid crystal display includes many components to thereby make it difficult to reduce production costs. In addition, a large-area substrate poses transportation problems. A liquid crystal panel is produced by forming respective optical function film/TFT element and light emitting element on a long thin-film-form film of organic resin and laminating the films by transferring. A base film serving as the substrate of a liquid crystal panel preferably has a thickness of 10 to 200 μm, a flexibility with a radius of curvature of up to 40 mm, and a thermal expansion coefficient of up to 50 ppm/°C. In addition, it more preferably undergoes mechanical and optical characteristics changes of up to ±5 % after a heat history of at least 200 °C.
