A display method of a three-dimensional picture image is provided which comprises a step for dividing and sampling a three-dimensional image space to be displayed into a plurality of two-dimensional images in a depth direction; a step for sequentially displaying each of the two-dimensional images; a step for observing each of the two-dimensional images by a naked eye through an optical system as a virtual image by the optical system; and a step for moving a position of the virtual image in an optical axis direction by changing an optical distance between the optical system and each of the two-dimensional images within an afterimage time of the naked eye, wherein each of the two-dimensional images is a two-dimensional image within the three-dimensional image space corresponding to each moving position of the virtual image and is set to be displayed at a time point of each moving position of the virtual image.
