Three dimensional image display device.

An autostereoscopic system with a flat screen and a cylindrical lens grid plate (3D image perception without additional optical aids) to the viewer offer maximum freedom of movement, in which the reproduction quality is as uniform as possible, and largely exclude blurs, crosstalk and other adverse visual effects. Measures to optical correction based on plane-parallel variable positioning of flat screen (1A, 1P) and cylindrical lens grid plate (2) and the cylindrical lens grid plate (2) on increasing thickness (T) and decreasing pitch width (P) of the cylindrical lenses (6) , from the center (3) to the vertical side edges (4, 5) down. Here, the pixel or image strip spacing on the screen (1A, 1P) remains constant.
