Tridimensional optical element and manufacturing method therefor

The invention discloses a tridimensional optical element and a manufacturing method therefor.The tridimensional optical element comprises a substrate, an orientation film and a liquid crystal layer.The orientation film comprises at least one first region and at least one second region.The liquid crystal layer arranged on the orientation film comprises a first and a second liquid crystal molecules.The first liquid crystal molecule is equipped with a first pre-tilt angle corresponding to the first region of the orientation film.The second liquid crystal molecule is equipped with a second pre-tilt angle different from the first pre-tilt angle corresponding to the second region of the orientation film.In addition, the fast axle of the first liquid crystal molecule generally lies toward the same direction with that of the second liquid crystal molecule and the slow axle of the first liquid crystal molecule generally lies toward the same direction with that of the second liquid crystal molecule.According to the tri
