In the vehicular display device 1 as above, the display light L1 corresponding to information to be displayed, emitted from the emitting portion 2, is projected onto the reflection portion 3 through the cross point CP. Then, the reflection portion 3 in the vehicular display device 1 reflects the display light L1 to the windshield WS serving as the display surface. The vehicular display device 1 causes the display light L1 reflected from the reflection portion 3 to the windshield WS, to reach the windshield WS through the optical-path opening 4a and the transparent covering member 4b. Then, the display light L1 having reached the windshield WS from the vehicular display device 1 is reflected from the windshield WS to the eye point EP. Due to this configuration, the vehicular display device 1 displays, on the windshield WS, the display image VI due to the display light L1. The display image VI is a reflected image due to the display light L1 reflected from the windshield WS to the eye point EP and is a so-called virtual image that can be visually identified from the eye point EP. In this manner, with the display light L1, the vehicular display device 1 can virtually display the display image VI regarding the vehicular information, on the windshield WS.
