Display apparatus and display unit

A display apparatus comprising a display unit that projects an image to a light transmissive display member, the display apparatus forming a virtual image of the image projected by the display unit on an opposite side to a user side with respect to the display member, wherein

• the display unit is configured to accommodate a display device that displays the image 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 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,
• an interval D12 between the first reflecting member and the second reflecting member and an interval DL1 between the first reflecting member and the image of the display device satisfy a relation of 3.0<D12/DL1<10.0 in the display unit,
• the opening of the housing includes a first end formed at a rim on a first reflecting member side of the opening and a second end formed at a rim on a second reflecting member side of the opening, and
• a display surface of the display device, where the image is displayed on the display device, is disposed so as to be located on the first reflecting member side with respect to a straight line connecting the first end and the second end.
