A naked-eye stereoscopic display apparatus satisfies θ=arctan {(Ax·px)/(Ay·py)}, GF=Bx·Lx/px, Ay≧2 and Bx≧2, Lx=α·px+β·py·tan θ, and GH=(α·px)2+(β·py)2. In these expressions, px is a pixel pitch in a horizontal direction, py is a pixel pitch in a vertical direction, Lx is a lens pitch of cylindrical lenses in the horizontal direction, θ is an inclination angle of cylindrical lenses, Ax and Ay are integers prime to each other, and α and β are integers. Bx is a minimum natural number in which a numeric value GF becomes an integer. When α0 is defined as the value of α that minimizes the numeric value GF, α0 is not a multiple of the number of types of color pixels. When Lx=δ·px is established, the naked-eye stereoscopic display apparatus satisfies tan θ=(7−δ)·(px/py) and 5.3≰δ≰5.4.
