OPTICAL DISPLAY, SEAT, AND VEHICLE

An optical display (10), a seat, and a vehicle. The optical display (10) comprises a housing (1), a light source unit (3), and a curved mirror (7). The light source unit (3) is fixed on the housing (1) and is used for emitting imaging light. The curved mirror (7) comprises a mirror body (72) and a connecting portion (74) protruding from the mirror body (72), the mirror body (72) is used for reflecting the imaging light outside the housing (1), and the connecting portion (74) abuts against and is fixedly connected to a first positioning surface (162). The curved mirror (7) is directly fixed on the first positioning surface (162) on the housing (1) by means of the connecting portion (74) without using an adapter such as a frame, thereby reducing the number of components of the optical display (10), improving the assembly precision of the optical display (10), simplifying the structure of the optical display (10), improving the precision of the optical path system of the optical display (10), and improving the o
