A method is provided of making a passive patterned retarder, in which a liquid crystal alignment surface is formed. The alignment surface 37 comprises sets of regions. Each region comprises a grating-like structure having elongate surface relief features aligned in the same alignment direction. The alignment directions of different sets are different from each other. The alignment surface is coated in a layer of fixable liquid crystal material 38 whose optic axis is oriented by the underlying grating-like structure. The liquid crystal material is then fixed so that the optic axis is defined and fixed by the underlying grating-like structures. |
