Abstract:
A display device according to the invention includes an image generating unit and a projection optical system. The projection optical system includes an optical element provided with a plurality of curved mirrors. The plurality of curved mirrors are arranged in a first direction so that the curved mirror positioned on a far side from the image generating unit has a greater inclination than that of the curved mirror positioned on a near side to the image generating unit. The plurality of curved mirrors include a curved mirror disposed in a position in a second direction equivalent to a thickness direction of the optical element that varies in the first direction.

Claim (Index 1):
A display device comprising:\n an image generating unit configured to emit light including image information; and a projection optical system configured to guide light from the image generating unit toward an exit pupil and generate an image by the light in a position of the exit pupil, wherein the projection optical system includes an optical element provided with a plurality of curved mirrors configured to reflect a portion of the light toward the exit pupil and transmit the other portion of the light, and the plurality of curved mirrors are arranged in a first direction, and the plurality of curved mirrors are configured so that the curved mirror positioned on a far side from the image generating unit has an inclination greater than that of the curved mirror positioned on a near side to the image generating unit, and the plurality of curved mirrors include a curved mirror positioned at z (\u03b7) that satisfies equation (1) below, in a second direction equivalent to a thickness direction of the optical element:\n Z (\u03b7)=1/tan \u03b2[(sin \u03b7 0 \u2212sin \u03b7)/cos \u03b7 0 \u2212(\u03b7 0 \u2212\u03b7)]\u2003\u2003(1) \n where, \u03b2: Refraction angle of light on surface of optical element on observer side \u03b7: \u03b7=arcsin (sin \u03b7/n) \u03b8: Exit angle of light from optical element n: Refractive index of medium of optical element \u03b7 0 : \u03b7 in a position where \u03b8 is maximum in optical element.
