摘要： The present invention provides a liquid crystal display element that exhibits a large potential-difference gradient due to inter-electrode distance in FFS mode or the like and contains one or more compounds selected from the group of compounds represented by General Formula (I) and one or more compounds selected from the group of compounds represented by General Formula (II). The liquid crystal display element of the present invention provides a liquid crystal display element which uses a liquid crystal composition with negative dielectric anisotropy and makes it possible to realize excellent display characteristics such as flicker when used in a liquid crystal display element that exhibits a large potential-difference gradient due to inter-electrode distance in FFS mode or the like, without deteriorating the burn-in characteristics of the display element or various liquid crystal-display-element characteristics such as dielectric anisotropy, viscosity, maximum nematic-phase temperature, nematic-phase stability at low temperatures, or γ1.

摘要： A liquid crystal composition and a method of manufacturing an optical film. The liquid crystal composition which may form a liquid crystal layer having excellent optical characteristics and a high surface hardness. The liquid crystal layer formed as described above may be used in various applications, and for example, may be disposed on the outermost surface of a display device, such as an LCD or an OLED, or at an outer side of a polarizing layer of the display in which the polarizing layer is disposed at a visible side, thereby serving as a liquid crystal layer which may solve a problem of degrading brightness occurring when an observer watches an image with polarizing sunglasses.

摘要： Disclosed are polymerizable mixtures comprising a functionalized ionic gemini surfactant and a thiol-ene crosslinking agent. The polymerizable mixtures that further comprise a polar solvent may be used to form the surfactant into a triply periodic multiply continuous lyotropic phase in the presence of the crosslinking agent. Upon crosslinking, the lyotropic phase morphology is substantially retained.

摘要： Methods of forming a liquid crystal blue phase from composite materials having a chiral nematic liquid crystal host and a bent-shape molecule are described. The stable temperature range of the liquid crystal blue phase may be improved by controlling the thickness of the composite materials. For example, a given composition may have a maximum stable temperature range for the liquid crystal blue phase at about 1 μm.
