Claim 4:
5. The polymerizable compound according to claim 1, wherein A22 denotes independently and, in case of multiple occurrence, independently of one another, a moiety of groups a) to e):
a) trans-1,4-cyclohexylene, 1,4-cyclohexenylene and 4,4′-bicyclohexylene, in which one or more non-adjacent CH2 groups may be replaced by —O— and/or —S— and wherein one or more H atoms may be replaced by a group L;
b) 1,4-phenylene, 1,3-phenylene, 4,4′-biphenylene, 2,5-thiophene and 2,6-dithieno[3,2-b:2′,3′-d]thiophene in which one or two CH groups may be replaced by N and where one or more H atoms may be replaced by a group L;
c) tetrahydropyran-2,5-diyl, 1,3-dioxane-2,5-diyl, tetrahydrofuran-2,5-diyl, cyclobut-1,3-diyl, piperidine-1,4-diyl, thiophene-2,5-diyl and selenophen-2,5-diyl, which may be substituted one or more groups L;
d) saturated, partially unsaturated or completely unsaturated, and optionally substituted, polycyclic radicals having 5 to 20 cyclic C atoms, of which one or more can also be replaced by heteroatoms,
or

e) cyclic imides:, where one or more H atoms may be replaced by a group L, and/or one or more double bonds may be replaced by single bonds, and/or one or more CH groups may be replaced by N.
