A method of arranging a plurality of infinity image displays to form a wide angle display. Displays are shaped in the form of spherical wedges and butted together to form tiers having the desired horizontal field of view and the tiers arranged vertically to form a continuous vertical field of view. To avoid mechanical interference tiers may be segments of spheres of different sizes and may still, if arranged so that the centers of all spheres of which tiers are segments are centered at the observer's eyepoint, provide a continuous display as seen by the observer.
