ABSTRACT:
An optical element and a process for producing the optical element are provided. The optical element includes a light transparent substrate and a first birefringence layer provided on the substrate. The first birefringence layer includes a polymerizable liquid crystal having rodlike molecules and a coupling agent and/or a surfactant that homeotropically align the polymerizable liquid crystal to form a crosslinked polymer in a state of homeotropic alignment. The crosslinked polymer has a three-dimensionally crosslinked structure wherein the polymerizable liquid crystal having rodlike molecules holds homeotropic alignment.
