This display screen turning apparatus (base for a display screen) includes a platelike base member so formed as to receive the load of a display body applied to a display screen support mechanism on a partial region and to warp in a direction opposite to the direction of deflection resulting from the load of the display body with a prescribed amount of warpage when not receiving the load of the display body, and the prescribed amount of warpage is so set that the surface of the base member is substantially flattened when the base member receives the load of the display body applied to the display screen support mechanism.
