Abstract
An image source, a display device, a head up display apparatus and a transportation equipment are disclosed. In the display device, the refractor is on a light exiting side of the image source component and changes an optical distance of the image light, so as to change the imaging distance of a virtual image formed by the image light; the processing portion is on a light exiting side of the refractor and reflects the image light to form the virtual image. The image source component includes a light modulation layer, the light modulation layer converts the incident light-source light into image light and emits the image light from the light exiting surface of the image source; the light compensation component causes the light-source light to be incident into different positions of the light incident surface of the light modulation layer with a refraction angle.
