Abstract:
1. A naked-eye stereoscopic display apparatus comprising: a two-dimensional display in which color pixels are arrayed individually in a horizontal direction and a vertical direction, and color pixels of a same color are arrayed in the vertical direction; and a lenticular sheet including a plurality of cylindrical lenses arrayed in parallel to one another, the lenticular sheet being arranged on the two-dimensional display so that viewpoint images displayed on the color pixels is observed through the cylindrical lenses, wherein, when a pixel pitch in the horizontal direction of the color pixels is defined as px, a pixel pitch in the vertical direction of the color pixels is defined as py, a lens pitch of the cylindrical lenses in a horizontal direction is defined as Lx, an inclination angle of boundary lines among the cylindrical lenses with respect to the vertical direction of the two-dimensional display is defined as θ, types of the color pixels are a natural number of 3 or more defined as D, Ax and Ay are integers prime to each other, and α and β are integers, then Expressions (1) to (5) are satisfied: where Bx is a minimum natural number in which a numeric value GF shown in Expression (2) becomes an integer, and α when δ is defined as a number that satisfies Expression (6), then either Expression (7) or Expression (9) is satisfied:
