In the windshield, a first region where the first display light is incident and a second region where the second display light is incident overlap with each other, the second projection part includes a filter part (22) that cuts light in a predetermined wavelength region from the second display light, and the predetermined wavelength region is a wavelength region of the light diffracted by the hologram.",
