PROBLEM TO BE SOLVED: To provide a head-up display system that suppresses double images from a combiner by eliminating or reducing a reflection of a refracted image from the back surface of the combiner.SOLUTION: A combiner 204 includes a polarizing layer 205 having a tilted axis 209. For a uniaxial absorbing axis within this combiner 204, no light with a propagation direction substantially aligned with the tilted axis 209 is absorbed. The tilted axis 209 is oriented at a non-zero angle with respect to the plane of the polarizing layer 205. A refracted ray 214 from a polarized image generation system 201 can have a portion of its light polarized along the tilted axis 209, and the electric field is not orthogonal to the tilted axis 209 and is thereby attenuated by the tilted axis 209.SELECTED DRAWING: Figure 2 |
