Abstract: An image display apparatus according to an aspect of the present technology includes a light source, an image generator, and a projection optical system. The image generator modulates light emitted from the light source and generates image light. The projection optical system includes a lens system and a concave reflective surface. The lens system is configured on a basis of a reference axis at a position on which the generated image light is incident, and has a positive refracting power as a whole. The concave reflective surface is configured on a basis of the reference axis, and reflects the image light emitted from the lens system toward a projection target. In addition, the concave reflective surface reflects at least one or more light beams included in the image light incident on the concave reflective surface, toward a direction that intersects with a direction along the reference axis at an angle of 80 degrees or more.

Abstract: The present image display apparatus includes: a light source; an image generation unit; and a projection optical system. The image generation unit generates image light on the basis of light from the light source. The projection optical system includes a first lens system, a first reflective optical system, a second lens system, and a second reflective optical system. The first lens system refracts the generated image light. The first reflective optical system has first and second reflection surfaces that fold back and reflect the image light refracted by the first lens system. The second lens system refracts the image light reflected by the second reflection surface. The second reflective system has a recessed reflection surface for reflecting the image light refracted by the second lens system toward an object to be projected. Further, the image display apparatus is configured to satisfy the following relationship: 5×10−7
