Abstract:
A display device includes a first diffraction element configured to diffract image light and a second diffraction element disposed on as optical path between a light source and the first diffraction element. The first and the second diffraction element emit light beams that have highest diffraction efficiencies in one direction when a single wave light enters from directions of normals. If the sum of the number of reflections of light and the number of times of intermediate image generation between the second diffraction element and the first diffraction element is an even number, in the first and the second diffraction element, the directions of the diffraction light having the highest diffraction efficiencies are output when light enters from the directions of the normals are the same with respect to the directions of the normals to the incident planes. If the sum is an odd number, the directions are opposite.

Claim (Index 1):
A display device comprising:\n an image light generation device configured to output an image light; a first diffraction element configured to diffract the image light that has entered a first incident plane such that the image light is directed to an eye of an observer; and a second diffraction element disposed on an optical path between the image light generation device and the first diffraction element, the second diffraction element being configured to diffract the image light that has entered a second incident plane such that the image light is directed to the first diffraction element, wherein the first diffraction element has highest diffraction efficiency in a first direction when light enters from a direction of a normal to the first incident plane, the second diffraction element has highest diffraction efficiency in a second direction when light enters from a direction of a normal to the second incident plane, the first diffraction element and second diffraction element are disposed such that, if the sum of the number of reflections of light and the number of times of intermediate image generation between the second diffraction element and the first diffraction element is an even number, when viewed from direction of normal to virtual plane that include a normal to the first incident plane and a normal to the second incident plane, the direction of the first direction with respect to the direction of the normal to the first incident plane and the direction of the second direction with respect to the direction of the normal to the second incident plane are the same as each other, and the first diffraction element and the second diffraction element are disposed such that, if the sum of the number of reflections of light and the number of times of intermediate image generation between the second diffraction element and the first diffraction element is an odd number, when viewed from the direction of the normal to the virtual plane that include the normal to the first incident plane and the normal to the second incident plane, the direction of the first direction with respect to the direction of the normal to the first incident plane and the direction of the second direction with respect to the direction of the normal to the second incident plane are different from each other.
