<p>PROBLEM TO BE SOLVED: To provide a vehicular projection type display device capable of displaying image on a window while ensuring field of view through the window of a crew.SOLUTION: A plurality of reflection parts 20 are aligned on a windshield 12, such that superimposed image is displayed on the windshield 12 by reflecting image light from an image projection device 18 on the reflection parts 20. In addition, the plurality of reflection parts 20 are arranged on the windshield 12 with an interposed mutual interval SPh in transverse direction. The width WDh of reflection parts 20 in the transverse direction of the windshield 12 is 2 mm or less, since a human has the minimum pupil diameter of approximately 2 mm in a bright place. In addition, the mutual interval SPh between the reflection parts 20 has the same or larger width than the width WDh of the reflection parts 20. A field of view of an occupant through the windshield 12 is therefore sufficiently ensured.</p> |
