Abstract
The invention relates to an electro-optical liquid-crystal display which contains, as dielectric, a liquid-crystalline medium having negative dielectric anisotropy and includes a backlight which essentially only emits light having a wavelength of 400 nm or more or has, between the liquid-crystal layer and the backlight, a cut-off filter which essentially only allows light having a wavelength of 420 nm or more to pass through. In particular, the liquid-crystalline medium comprises in which the parameters have the meanings indicated in claim, and a further (second) dielectrically negative component (component B). Very particular preference is given to the use of the liquid-crystalline media in an electro-optical display, particularly in an active-matrix display based on the VA, ECB, PSVA, FFS or IPS effect and very particularly in displays which use an LED backlight.
