Abstract
The purpose of the present invention is to provide a head-up display device capable of providing countermeasures against solar light without using a shutter or a reflective polarizer film. A case includes a first shielding part and a second shielding part that sandwich optical paths between a first mirror and a second mirror and extend to the vicinity of a cross point where the optical paths intersect. The tip end of the first shielding part is located in front of the tip end of the second shielding part. A display is arranged below the second shielding part and in front of a line that connects the tip end of the first shielding part and the tip end of the second shielding part. The first and second shielding parts block external light entering from above an opening and block external light that may enter the case and travel toward the first mirror after reflecting from the second mirror.
