<p>An autostereoscopic display lens arrangement comprises an array (9) of parallel lenticular lenses (11), wherein the lens array comprises first and second materials of different refractive indices (60,62) sandwiched between planar substrates, with the interface between the first and second materials defining the lens surfaces. The first material has a refractive index n1, the lens array has a lens pitch p and the lenticular lenses have a radius of curvature at their centre of R, and the lenses satisfy n1 (p/2R)>0.6. This arrangement gives reduced banding and loss of intensity at steep angles when used in an autostereoscopic display.</p> |
