Display device and vehicle

The embodiment of the invention provides a display device and a vehicle, and relates to the technical field of light display. The display device can be installed in a vehicle, and the size of the display device is smaller than that of an existing display device. In the display device, an image generation unit is used for generating first image light and second image light; the first optical device is used for receiving the first image light, configuring a first focal power value for the first image light, generating third image light and coupling the third image light into the optical waveguide from the coupling-in area of the optical waveguide; the second optical device is used for receiving the second image light, configuring a second focal power value for the second image light, generating fourth image light and coupling the fourth image light into the optical waveguide from the coupling-in area of the optical waveguide, and the first focal power value is different from the second focal power value; the optical waveguide is used for coupling out the third image light from a coupling-out area of the optical waveguide; and the optical waveguide is also used for coupling out the fourth image light from the coupling-out area of the optical waveguide.
