And an eyepiece optical system including a concave mirror 56. Reference numeral 62 is the viewer's head, and 63 is the viewer's eyeball. The image display device 53 is illuminated by a backlight light source (51 and 52) with a substantially parallel light flux from the back surface to form a two-dimensional image. Then, the relay optical system (54 and 55) projects the real image of this two-dimensional image in front of the concave mirror 56 as an aerial image. This real image is further enlarged and projected as a virtual image in the air in front of the eyeball 63 by the concave mirror 56. The projection position of the virtual image can be adjusted appropriately according to the diopter of the eyeball 63, and the enlarged image of the two-dimensional image displayed on the video display device 53 is viewed. The main role of the imaging lens 55 is to project the real image of the light emitting element 51 of the image display device 53 in front of the concave mirror 56. As a result, the light flux at the image forming lens 55 is narrowed down, so that not only the lens of the image forming lens 55 can be downsized, but also the occurrence of aberration of the image forming lens 55 can be easily suppressed. The backlight light sources (51 and 52) illuminate the LCD type image display device 53 with a substantially parallel light flux from the back in order to obtain a good image from the image display device 53. That is, the collimator lens 52 projects the image of the light emitting element 51 toward infinity. The field lens 54 relays the image of the light emitting element 1 generated at infinity in the vicinity of the imaging lens 55 as a real image.

The image display unit shown in FIG. 4B can provide a stereoscopic image by displaying images with parallax on the left and right.

When the concave mirror 72 is in use, the concave mirror is expanded forward, and when not in use, the concave mirror 72 is retracted upward and rearward. As shown, there is a method in which the entire concave mirror 76 can be rotated from the front to the upper rear. The images from the image display devices 71 and 73 are reflected by the inner reflection plate of the concave mirror 72 and enter the eyes. This embodiment can use a video display device that is relatively larger than that of the fourth embodiment, so that it is possible to present a high resolution video.

Further, the present invention is not limited to the above embodiment, but various modifications can be made. For example, the control box may be on the lid instead of on the side of the seat or on the ceiling. In short, it should be a place near the seat where the viewer's hand can reach and operate. Further, although the image of the image display device is reflected and projected into the eyes of the viewer using the concave mirror, it goes without saying that a magnifying optical system using a convex lens may be used. Furthermore, although the example has been described in which it is provided in the seat of a vehicle such as a passenger plane, it may be provided in a seat in the room for training, education, etc., not limited to the vehicle.
