Head up display device |
| abstract |
The present invention provides a head-up display device which is excellent in visibility when viewed through polarized sunglasses and is excellent in heat resistance. The head-up display device of the present invention has: a display that emits projection light; at least one reflector that reflects projection light; a housing that has an opening and houses the display and the reflector inside; and a cover member that covers the opening And a polarizing plate with a phase difference layer disposed on the inner side of the casing of the cover member, and sequentially including a phase difference layer and a polarizing element from the side of the cover member. The in-plane retardation Re (550) of the retardation layer is 100 nm to 200 nm, and the head-up display device of the present invention has a reflection angle of 30° or less with respect to the windshield of the projection light emitted from the casing through the opening or It is composed of 40° or more. |
