The present invention provides an anisotropic optical element having
optical properties that are anisotropic with respect to a direction of a
normal to an element plane, being capable of preventing a projection
screen or the like from mirroring a light source. The anisotropic optical
element includes an oriented cholesteric liquid crystalline reflective
layer made from a polymerizable cholesteric liquid crystal. A mean
direction of directions of helical axes (main direction of helical axes)
in liquid crystal domains of the liquid crystalline structure of the
cholesteric liquid crystalline reflective layer is tilted at a
predetermined angle with respect to a direction of a normal to the layer
plane.
