A method of manufacturing a birefringent film is provided, by which a
birefringent film including a liquid crystal compound birefringent layer
and another birefringent layer can be manufactured so as to have a
reduced thickness in a reduced number of process steps. In the
manufacturing method, a non-liquid crystal polymer birefringent layer
that has been subjected to an aligning treatment is used as an alignment
layer for a liquid crystal compound. According to the manufacturing
method, the process step of separately preparing an alignment layer and
the need for the additional alignment layer can be eliminated, thereby
allowing the total thickness of the birefringent film to be reduced.
