Uniaxially stretched negative birefringent film and liquid crystal display having the same

摘要

Disclosed is a uniaxially stretched birefringent film having a negative birefringence, comprising a graft polymer which is obtained by grafting, through addition-polymerization, at least one monomer selected from styrene and derivatives thereof to a polymer having an unsaturated double bond. The liquid crystal display provided with the birefringent film is also disclosed.
