The present invention relates to liquid-crystal media and liquid-crystal displays (LC displays) comprising these media with homeotropic (vertical) alignment of the liquid-crystalline medium (LC medium). The LC medium having positive dielectric anisotropy according to the invention comprises particles having a mass of at least 450 Da which have been functionalised by a polar, organic anchor group. It is preferably stabilised by a polymerisable component.
