DISPLAY DEVICE AND VEHICLE

A display apparatus and a transportation means are provided. A prism group (103, 803, 1003) is used to change optical paths of different imaging sub-light. A light path structure is simple, a reuse rate of a device is high, and an image basically has no crosstalk. The display apparatus includes: a projection module (101, 801, 1001), a deflection reflection component (102, 802, 1002), and a prism group (103, 803, 1003). The projection module (101, 801, 1001) is configured to project a first path of imaging light to the deflection reflection component (102, 802, 1002). The deflection reflection component (102, 802, 1002) is configured to: reflect the first path of imaging light to generate at least two paths of imaging sub-light, and respectively reflect the at least two paths of imaging sub-light to the prism group (103, 803, 1003) at at least two angles. The prism group (103, 803, 1003) is configured to: enable the at least two paths of imaging sub-light to propagate through different paths, and emit the at least two paths of imaging sub-light.
