Abstract

An aerial image display device is capable of changing a depth of a virtual image viewed by an observer without changing a distance between at least one display device and an optical element forming the virtual image. The aerial image display device includes a display device, optical elements, and a reflecting member. The optical elements are installed corresponding to different display regions of a display surface of the display device and sequentially arranged along the display surface in an observation direction of an observer. The optical element is installed obliquely with an angle of about 45° in a −X direction when viewed from the display surface of the display device. The optical element is installed obliquely with an angle of about 45° in an X direction when viewed from the display surface of the display device.
