Since the demonstration of projection-type autostereoscopic lenticular 3D display using an array of projection lenses in front of a photographic film of view pictures with parailax, the feasiblity of the same type 3D TV display has been anticipated if view pictures are reproduced on an array of LCD panels. This paper describes an experimental verification of the feasibility. The experimental dispaly consists of three parts : a set of 12 projection lenses in front of 12 LCD panels illuminated by 12 lamps, a transformation optic consisting of an off-centered Fresnel lens and a convex mirror, and a lenticular screen for displaying 3D image to observers. The transformation optic reduces the separation of projenction lenses to obtain the condition of easy viewing by human observers. A dynamic 3D image is seen on a lenticular screen with 460mmH×360mmV size by observers without glasses. The reference viewing zone has 420m width 1100mm in front of the lenticular screen. Observesr can see 3D image from any position in a deep viewing zone.
