A display apparatus according to the present technology includes a display unit that projects an image to a light transmissive display member, and the display apparatus forms 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. 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, 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. The first reflecting member and the second reflecting member are disposed so as to satisfy a relation of 0.2 < D12/Lv < 1.3. Where Lv is a length in a longitudinal direction of the virtual image of the image, and D12 is an interval between the first reflecting member and the second reflecting member in a center optical path.
