The invention provides a three-dimensional display, a production method and a control method thereof; the three-dimensional display is suitable for an observer to watch when wearing glasses which are provided with two lenses orthogonalized in the polarization direction; and the three-dimensional display comprises a display panel and a liquid crystal phase modulation panel. The display panel is provided with pixels and a polarizing plate between the pixels and the glasses; the polarizing plate is provided with a penetration shaft; and the display panel is suitable for displaying images. The liquid crystal phase modulation panel is located between the polarizing plate and glasses and provided with a liquid crystal layer and an alignment layer adjacent to the display panel; wherein, the angle formed between the alignment direction of the alignment layer and the penetration shaft is actually n multiplying 45 degrees; the absolute value of n is an integer; the liquid crystal phase modulation panel is suitable for providing the phase retardation; by adjusting the phases of images, the liquid crystal phase modulation panel outputs the images with three-dimensional information; and the liquid crystal phase modulation panel does not have any polarizing plate.
