摘要：The invention concerns a transparent thin liquid crystal alignment film ()including liquid crystals () within a polymerised liquid crystal composition, the film ()

comprising a first main surface (), a second main surface () and a bulk () comprisedbetween said opposed two main surfaces (), for which: ⋅ in the vicinity of the first mainsurface (), the liquid crystals () are aligned along a main first direction, ⋅ in the vicinity ofthe second main surface (), the liquid crystals () are aligned along a main second direction,different from the first direction, and in between, the bulk () comprises liquid crystals ()maintained in an isotropic orientation. The invention concerns also a process ofmanufacturing such a liquid crystal alignment film () and a polarization-independentspatial phase modulator including such a liquid crystal alignment film ().
