Abstract:
An optical waveplate is provided. The optical waveplate includes a first birefringent film including optically anisotropic molecules arranged to form a first twist structure. The optical waveplate also includes a second birefringent film including optically anisotropic molecules arranged to form a second twist structure, the second birefringent film being stacked with the first birefringent film. The optically anisotropic molecules at a first portion of the first birefringent film adjacent an interface between the first birefringent film and the second birefringent film are configured with a first azimuthal angle. The optically anisotropic molecules at a second portion of the second birefringent film adjacent the interface are configured with a second azimuthal angle. The first azimuthal angle is substantially the same as the second azimuthal angle.
