PROBLEM TO BE SOLVED: To provide a head-up display (HUD) device having high mountability on a mobile body.SOLUTION: The HUD device displays a virtual image that can be visually recognized as an image by a crew. The HUD device includes: an illumination light source part 10 emitting illumination light; an image display panel 40 transmitting the illumination light from the illumination light source part 10 side to outgo as display light from a display screen 44 so as to display an image; and a projection lens 30 disposed between the illumination light source part 10 and the image display panel 40 and projecting the illumination light from the illumination light source part 10 side onto the image display panel 40. The image display panel 40 is disposed as inclined in such a manner that a normal direction ND of the display screen 44 intersects an optical axis OA of the illumination light source part 10. The projection lens 30 is disposed as inclined in such a manner that a radial direction DD of the projection lens 30 is aligned to a tangential direction TD of the display screen 44.SELECTED DRAWING: Figure 3

    【課題】移動体への搭載性が高いHUD装置を提供する。【解決手段】HUD装置は、画像を乗員により視認可能に虚像表示する。HUD装置は、照明光を発する照明光源部10と、照明光源部10側からの照明光を通過させ、表示光として表示面44から射出することで画像を表示する画像表示パネル40と、照明光源部10と画像表示パネル40との間に配置され、照明光源部10側からの照明光を画像表示パネル40に投射する投射レンズ30と、を備える。画像表示パネル40は、照明光源部10の光軸OAに対して表示面44の法線方向NDが交差するように、傾斜配置される。投射レンズ30は、当該投射レンズ30の径方向DDを表示面44の接線方向TDに合わせるように、傾斜配置されている。【選択図】図3
