    • A display apparatus comprises a spatial light modulator and optical elements in series therewith. The optical elements provide a first parallax element being a parallax barrier capable of directing light output from the display apparatus into a first plurality of viewing windows, and a second parallax element capable of directing light output from the display apparatus into a second plurality of viewing windows. In a first mode, the first and second parallax elements have substantially no directional effect on the light output from the display apparatus. In a second mode, the first parallax element directs light output from the display apparatus into the first plurality of viewing windows and the second optical element has substantially no directional effect. In a third mode, the second optical element directs light output from the display apparatus into the second plurality of viewing windows and the first parallax element has substantially no directional effect.

    • Manufacture of a birefringent liquid crystal cell is performed as follows. A layer of isotropic material having an outer surface which is shaped with a surface relief structure and is provided with a liquid crystal alignment property is formed. A flexible sheet having an outer surface provided with a liquid crystal alignment property is formed. A curable birefringent liquid crystal material is applied to one or both of the layer of isotropic material and the flexible sheet. The flexible sheet is applied over the layer of isotropic material with the outer surfaces of the layer of isotropic material and the flexible sheet facing one another with the liquid crystal material therebetween, thereby to form a liquid crystal cell. The liquid crystal material is cured and the flexible sheet is removed from the liquid crystal cell.

    • A birefringent lens structure comprises a birefringent lens array capable of directing light of a given polarisation into a directional distribution, the birefringent lens comprising a solid birefringent material and an isotropic material having an interface having a refractive structure. A switchable liquid crystal layer capable of rotating the polarisation of light passing therethrough is arranged adjacent the first birefringent material. The interface between the birefringent material and the liquid crystal layer has an alignment microstructure providing alignment of the birefringent material and the liquid crystal layer. A pair of electrodes for applying an electric field to switch the liquid crystal are arranged with both the lens array and the switchable liquid crystal layer therebetween and a conductive material is incorporated in the lens array to reduce the voltage drop across the lens array. To reduce reflection, the interface between the birefringent material and the isotropic material has an interface having alignment microstructure providing alignment of the birefringent material, and the refractive index of the isotropic material is substantially equal to the extraordinary refractive index of the birefringent material.
