    Abstract: An optical system includes a first expansion region that expands a luminous flux traveling in a first direction by splitting and duplicating it into luminous fluxes traveling in a second direction intersecting the first direction to increase the number of luminous fluxes, and a second expansion region that expands the luminous fluxes traveling in the second direction by splitting and duplicating them to increase the number of luminous fluxes. The first expansion region has a central region that contains a center of the first expansion region, and an end region that lies on at least one end side of the first expansion region. The end region has a diffracted light quantity less than half the diffracted light quantity in the central region.

    Abstract: A head-up display is configured to project an image on a transparent reflection member to cause an observer to visually recognize a virtual image, and includes a display device configured to display the image, and a projection optical system configured to project the image displayed by the display device as the virtual image for the observer. The projection optical system is configured to form the image as an intermediate image, and includes a first optical element configured to condense light, a first lens configured to condense light, and a second optical element configured to diffuse light. The first optical element, the first lens, and the second optical element are disposed in this order along an optical path from the display device.

    Abstract: A display apparatus includes a display unit that projects an image to a light transmissive display member. The display unit is configured to accommodate a display device and a projection optical system that projects the image displayed on the display device to the display member in a housing including an opening through which projected light is output. The projection optical system includes a first reflecting member disposed on a display device side and a second reflecting member disposed on an opening side in an optical path extending from the display device to the opening. A reflection surface of the first reflecting member that reflects the image displayed on the display device has a convex shape of a free-form surface, and a reflection surface of the second reflecting member that projects the image to the display member has a concave shape of a free-form surface.
