  The present invention provides a compound represented by formula (i), a liquid crystal composition using the compound, and a liquid crystal display device using the liquid crystal composition. The compound represented by formula (i) has a partial structure K i1 represented by any of general formulas (K-1) to (K-17) and further has ring B having at least two P-Sp- groups. Therefore, when used for a liquid crystal composition, the compound adsorbs to substrates sandwiching the liquid crystal composition (liquid crystal layer) and allows liquid crystal molecules to be held such that they are aligned in a vertical direction without a PI layer, and improved alignment stability and low-temperature storage stability can be achieved.

  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.
