PROBLEM TO BE SOLVED: To provide a compact image display device that has high visibility even when positions and spaces are limited for attaching a head-up display.SOLUTION: An image display device 10 includes a projection port 301 that projects image display light generated on the basis of image signals, and a combiner 400 that reflects the image display light projected from the projection port 301 to present a virtual image. The combiner 400 has a reflection surface 410, and the curvature in a specific direction along the reflection surface 410 is reduced as a distance from the projection port 301 increases. The reflection surface 410 of the combiner 400 may be formed of a biconic surface. |
