The invention provides a small HUD device with high reliability of image display and high thermal reliability. An HUD device (1) is provided with: an image display unit (2) provided with a display panel (liquid crystal panel) (22) for displaying an image; and an optical system (3) that projects image light of the displayed image onto a windshield of the vehicle and allows a virtual image of the image to be visually recognized by the light reflected by the windshield, and an effective display region (22a) of the image display unit (2) in which the image is displayed is set in a region biased toward one end of the display panel (22). An optical system (3) is provided with: a first reflection unit (31) that reflects image light emitted from an image display unit (2); and a second reflection section (32) that reflects the reflected light of the first reflection section (31) toward a windshield. The image display unit (2) is disposed so as to face the first reflection unit (31), and the display panel (22) is disposed so that one end thereof faces the second reflection unit side (32).

    本发明提供图像显示的可靠性高且热可靠性高的小型HUD装置。HUD装置(1)具备:图像显示部(2),具备显示图像的显示面板(液晶面板)(22);以及光学系统(3),将所显示的图像的图像光投射到车辆的挡风玻璃上,通过被挡风玻璃反射的光而能够目视确认图像的虚像,图像显示部(2)的显示图像的有效显示区域(22a)设定在偏向显示面板(22)的一方的端部的区域。光学系统(3)具备:第一反射部(31),反射从图像显示部(2)射出的图像光;以及第二反射部(32),将第一反射部(31)的反射光朝向挡风玻璃反射。图像显示部(2)与第一反射部(31)对置配置,显示面板(22)以一方的端部朝向第二反射部侧(32)的姿势配置。
