The instant invention relates to mesogenic media comprising one or more compounds of formula D
wherein the parameters are as specified in the text, preferably to mesogenic media showing a blue phase, preferably stabilised by a polymer, and their use in electro-optical light modulation elements and their respective use in displays, as well as to such devices.
The present invention relates to a liquid crystal display device that includes a particular color filter containing a material containing chiral liquid crystals and a particular dye and/or pigment.
The present invention provides a liquid crystal display device that can prevent a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and solve the problem of display defects, such as white spots, variations in alignment, and burn-in.
Because liquid crystal display devices according to the present invention characteristically prevent a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and reduces the occurrence of display defects, such as burn-in, the liquid crystal display devices are particularly useful as liquid crystal display devices in IPS mode and FFS mode for active-matrix driving and can be applied to household electrical appliances, automobiles, production facilities, measuring and analytical instruments, and communication devices.
