1. A liquid crystalline medium comprising
a polymerizable component A) comprising one or more polymerizable compounds, and a liquid-crystalline component B), hereinafter referred to as “LC host mixture”, comprising one or more mesogenic or liquid-crystalline compounds, wherein component B) comprises from 0.01 to 3% of one or more compounds of formula A in which the individual radicals, on each occurrence identically or differently, and each, independently of one another, have the following meaning: R1, R2 are alkyl, alkoxy, oxaalkyl or alkoxyalkyl having 1 to 9 C atoms or alkenyl or alkenyloxy having 2 to 9 C atoms, all of which are optionally fluorinated, L1, L2, L3 are F or Cl. |
