Abstract
The present display device is a retinal scan display device including: a projection optical system configured to project an image to a retina of an eye; a distortion correcting unit configured to correct a distortion of the image; an image inverting unit configured to invert the image; and a storage unit configured to store correction data for correcting the distortion of the image when the image is projected to a left eye and correction data for correcting the distortion of the image when the image is projected to a right eye, wherein, based on a switching signal that represents that a side at which the projection optical system is arranged has been switched from one eye side to the other eye side, the distortion correcting unit performs distortion correction, by switching from correction data corresponding to one eye to correction data corresponding to the other eye, and the image inverting unit performs image inversion.
