A lenticular lens having an array of elongate lenticular elements extending parallel to one another, the array having a first edge and a second edge extending parallel to the elongate lenticular elements; and a central line that is centered between the first edge and the second edge; characterized in that the focal length of the lenticular elements gradually decreases from the first edge of the array towards the central line as well as from the second edge of the array towards the central line. This improves the angular performance of the lenticular lens, so that at short viewing distances the image quality near the edges of the display is not impaired.
