Abstract:
1. An image combiner comprising: a lens element, including a convex lens and a concave lens, that guides a light flux from an image forming means; a substrate disposed in front of a user's eye, the substrate being transparent to visible light, and introducing the light flux emitted from the lens element; a reflection region inner-reflecting the light flux introduced from the image forming means into the substrate, the reflection region being a part of one surface of the substrate; and a polarization beam splitter to which the light flux reflected at the reflection region enters twice and which makes the light flux entering for a second time incident on the user's eye outside the substrate, the polarization beam splitter being installed in the substrate, wherein at least an angle θ an inclination direction of the light flux heading into the user's eye relative to the line that is perpendicular is set so to make a display position of a virtual image of the display surface to be at a position in an obliquely downward direction from the user's eye.
