Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a headup display apparatus for vehicles, the headup display apparatus being capable of suppressing deterioration of luminance of virtual images, while avoiding a cost increase.

SOLUTION: This headup display apparatus for a vehicle is provided with: a light emitting unit 70 having at least a light emitting body 72 that emits output light L2; a liquid crystal display 20 which emits display light L1; a concave mirror 41 which reflects the display light L1; and a housing 80 which houses the light emitting unit 70, the liquid crystal display 20, and the concave mirror 41. The output light L2 that has been emitted from the light emitting body 72, and the display light L1 that has been reflected by the concave mirror 41 are radiated to a windshield 13 through a translucent cover 85, and a virtual image V obtained by means of the radiation is visually recognized by a driver 14. The light emitting unit 70 is disposed inside of the housing 80 such that the light emitting unit faces the windshield 13 with the translucent cover 85 therebetween.
