<p>An autostereoscopic device is provided with: a two-dimensional display having colored pixels that are horizontally and vertically arranged; and multiple cylindrical lenses (12) through which the colored pixels are observed, and which are arranged parallel to each other. Px is taken as the horizontal pixel pitch of the colored pixels, py is taken as the vertical pixel pitch, Lx is taken as the horizontal lens pitch of the cylindrical lenses (12), and ? is taken as the angle of inclination of the boundary lines (BL) in the vertical direction. Ax and Ay are relatively prime natural numbers, Ax is greater than or equal to 2, and Bx is the smallest natural number in which the number GF indicated in formula (2) is an integer. Px, py, Lx and ? satisfy the relational expressions represented by formulas (1) to (3). ?=arctan{(Ax·px)/(Ay·py)}···(1) GF=Bx·Lx/px···(2) Ay?Bx?2 and Ax?2···(3)</p> |
