Abstract
An image display apparatus includes an image forming unit and a vehicle provided with the image display apparatus. The image forming unit includes a light source unit configured to emit light, an optical scanner configured to scan the light emitted from the light source unit two-dimensionally in a main scanning direction and a sub-scanning direction, and an intermediate image forming unit configured to form an intermediate image by the light scanned by the optical scanner. The image forming unit satisfies 0.3<Rm/L<3, where Rm denotes a radius of curvature of the intermediate image forming unit in the main scanning direction, and L denotes distance between a reference point when the optical scanner deflects and scans the light and a center of the intermediate image formed on the intermediate image forming unit. In the vehicle, the image display apparatus indicates the intermediate image to a driver as a virtual image.
