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
a) a (first) dielectrically negative component (component A) which consists of one or more dielectrically negative compounds of the formula I
in which the parameters have the meanings indicated in claim
2
, 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.
本发明涉及一种电光液晶显示器,其包含作为介电体的具有负介电各向异性的液晶介质,并包括一个基本只发射波长为400 nm或更高的光的背光源,或在液晶层和背光源之间具有一个截止滤光器,其基本只允许波长为420 nm或更高的光通过。特别地,液晶介质包括a) (第一)介电性负组分(A组分),其由一个或多个式I中参数具有所述权利要求中所示含义的介电性负化合物组成,以及另一个(第二)介电性负组分(B组分)。特别优选使用该液晶介质于电光显示器中,特别是基于VA、ECB、PSVA、FFS或IPS效应的有源矩阵显示器中,并且特别是在使用LED背光源的显示器中。
