An autostereoscopic display apparatus includes a two-dimensional display including color subpixels arranged in horizontal and vertical directions, cylindrical lenses configured to observe the color subpixels therethrough, a temperature sensor measuring an ambient temperature of the cylindrical lenses, and a parallax image changer changing the parallax images based on the measured ambient temperature. px is a horizontal pixel pitch. py is a vertical pixel pitch. Lx is a horizontal lens pitch. θ is an inclined angle of boundaries of the cylindrical lenses to the vertical direction. Ax and Ay are relatively prime natural numbers. Ax is equal to or larger than two. Bx is a minimum natural number by which a value GF indicated in the formula (2) represents an integer value. px, py, Lx and θ satisfy relational expressions represented by the formula (1) to the formula (3). θ=arctan {(Ax·px)/(Ay·py)}  (1) GF=Bx·Lx/px  (2) Ay≧Bx≧2 and Ax≧2  (3)
