Abstract
The anisotropically intrinsic scattering and reflection of a sole cell of polymer network-90° twisted nematic liquid crystals (PN-90° TNLCs) without any polarizer are proposed. Light with specifically linear polarizations, incident from one direction, can penetrate the PN-90° TNLCs with applied voltage. The polarization direction of the output beam will be rotated 90°. The same linearly polarized light, incident from the other direction, will be scattered because it encounters the refractive indices mismatch of various LC domains. The reflection, resulting from the boundaries of LCs and polymers, also shows optical anisotropy. Such LC devices can be applied as scattering-type linear polarizers.
