To provide a windshield display device that can allow an image to be visible in a predetermined region or a larger region of a windshield while suppressing an increase in the scale of a light source.SOLUTION: A windshield display device to allow an image to be visible for an occupant through a windshield V1 is configured to have projectors 1, 2 disposed at ends of the windshield V1 in a vehicle width direction of the vehicle and to project image light from the projectors 1, 2 toward a transparent screen 3 disposed to overlap the windshield V1. The transparent screen 3 reflects the image light toward either a first occupant C1 seated on the driver's seat of the vehicle or a second occupant C2, or toward both of them, allowing the image to be visible. Thus, the windshield display device is configured to be capable of projecting image light in a broader range to be visible for an occupant compared to a conventional HUD device, without increasing the scale of a light source.SELECTED DRAWING: Figure 2 【課題】光源の大型化を抑制しつつも、ウィンドシールドのうち所定以上の領域にて映像を視認させることが可能なウィンドシールド表示装置を実現する。【解決手段】ウィンドシールドＶ１を介して乗員に映像を視認させるウィンドシールド表示装置において、ウィンドシールドＶ１のうち車両の車幅方向における端部にプロジェクター１、２を配置し、ウィンドシールドＶ１に重ねて配置された透明スクリーン３に向けて当該プロジェクター１、２から映像光を投写する構成とする。透明スクリーン３は、車両の運転席に着座する第１乗員Ｃ１もしくは第２乗員Ｃ２またはその両方に映像光を反射し、映像を視認させる。これにより、光源を大型化することなく、従来のＨＵＤ装置よりも広範囲に映像光を投写でき、映像を乗員に視認させることが可能な構成となる。【選択図】図２
