Abstract
A display device includes an image forming unit, a projection unit, a main body, and a position correcting unit. The image forming unit includes a display surface and forms an image on the display surface. The projection unit projects a virtual image corresponding to an image on a target space by using output light from the image forming unit. The main body is equipped with an image forming unit and a projection unit. The position correcting unit changes a display position of a virtual image relative to the main body on the basis of an orientation signal representing an orientation of the main body. The position correcting unit includes a plurality of correcting units that change a display position of a virtual image by using different means. The position correcting unit selects at least one correcting unit from a plurality of correcting units in accordance with a frequency component of an orientation signal, and causes the selected correcting unit to change a display position of a virtual image.
