  We calculate the yield and elliptic flow of mid-rapidity dileptons emitted
from the quark-gluon plasma generated in Pb-Pb collisions at LHC. We use
relativistic anisotropic hydrodynamics for the 3+1 dimensional evolution of the
quark-gluon plasma and convolve this with the momentum-anisotropic local rest
frame production rate for dileptons. The effects of momentum anisotropy of the
quark distribution functions, viscosity to entropy density ratio, centrality of
the collisions, and initial momentum anisotropy on the results are investigated
and discussed.
