<p>A polymerizable liquid crystal is filled in grating grooves having a predetermined shape, and thereafter, the polymeric liquid crystal is cured to form a stripe structure comprising a uniaxial polymer liquid crystal having an orientation direction identical to the longitudinal direction of the grating grooves without using a liquid crystal alignment film. Consequently, it is possible to stably and effectively align the polymer liquid crystal without using an alignment film and to make the film thickness easily adjustable, whereby a polarization split element exhibiting a high and uniform split efficiency can be stably obtained.</p> |
