A display apparatus, a head-up display, and transportation equipment. In the display device, a first image source (11) comprises a first display area (110); a refractive element (2) is configured to refract image light emitted from at least partial area of the first display area (110); the image light refracted by the refractive element (2) is reflected by a first reflective element (31) and propagated to an observation area (5) to form a first virtual image; along the direction from a first end (e1) of the at least partial area to a second end (e2) thereof, an optical distance of at least part of the image light emitted from the at least partial area between a light incident surface (21a) of the refractive element (2) and a light exit surface (21) thereof is gradually decreased. According to the display apparatus, the requirement for the mounting angle of the first image source (11) used for realizing oblique imaging can be reduced, the occupied space is small, the structure is compact, the flexibility is improved, and the application range of the display apparatus for realizing oblique imaging is expanded.
