Further, in one embodiment of the present invention, the length direction of the first groove 13 is the same as the direction of one diagonal line of the substrate, and the length direction of the second groove 14 is the same as the direction of the other diagonal line of the substrate. The light exit end of the light tunnel 21 is inclined with respect to the second light guide 12 so that the image light emitted from the light exit end can enter the second reflecting surface 121 of the second light guide 12, and the image light is reflected by the second reflecting surface 121 at the same exit angle as the incident angle, reflected to the first reflecting surface 111, and reflected to the air at the same exit angle as the incident angle to form the upright floating real image 100.
