In recent years, in image display devices used in these fields, in order to improve amusement and visibility, development of stereoscopic display technology that can provide a high sense of presence has been attempted. Stereoscopic display devices can be broadly classified into those using parallax information and those using depth information. Those using disparity information can be further divided into those using polarized glasses and those not using them.
