Abstract
An optical system is an optical system that forms an image of light from a display panel on a retina when combined with an eyeball, the optical system including: a first refractive lens that collects light from the display panel; and a first diffractive lens provided between the first refractive lens and an image forming position, in which the first diffractive lens is configured such that a phase of light passing through an outer peripheral portion of the first diffractive lens is delayed from a phase of light passing through a central portion of the first diffractive lens.

An optical system that forms an image of light from a display panel on a retina when combined with an eyeball, the optical system comprising:
- a first refractive lens that collects the light from the display panel;
- and
- a first diffractive lens provided between the first refractive lens and the eyeball, wherein
- the first diffractive lens is configured such that a phase of light passing through an outer peripheral portion of the first diffractive lens is delayed from a phase of light passing through a central portion of the first diffractive lens.
A display device, comprising:
- a display panel;
- and
- an optical system that forms an image of light from the display panel on a retina when combined with an eyeball, wherein
- the optical system includes:
- a first refractive lens that collects the light from the display panel;
- and
- a first diffractive lens provided between the first refractive lens and the eyeball, and
- the first diffractive lens is configured such that a phase of light passing through an outer peripheral portion of the first diffractive lens is delayed from a phase of light passing through a central portion of the first diffractive lens.
