PROBLEM TO BE SOLVED: To attain improvement in visibility due to an enlargement or a distortion correction about images to be projected to a combiner as suppressing increase in the number of components, and attain miniaturization of a device.SOLUTION: An on-vehicle display device according to the present invention comprises: a display unit that implements an image display; a combiner that has a reflection surface, in which a display image by the display unit is projected on the reflection surface; a transmission type correction optical element that is located between the display unit and the combiner to make a distortion correction about the image to be projected to the combiner; and a fixed part that has the display unit, the combiner and the correction optical element attached, and is fixed to a vehicle via a fixing tool. The correction optical element has an enlargement function of the image.SELECTED DRAWING: Figure 3 【課題】コンバイナに投影される画像について拡大や歪み補正による視認性向上を部品点数の増加を抑えながら図りつつ、装置小型化を図る。【解決手段】本発明に係る車載用表示装置は、画像表示を行う表示部と、反射面を有し、表示部による表示画像が該反射面に投影されるコンバイナと、表示部とコンバイナとの間に位置されコンバイナに投影される画像についての歪み補正を行う透過型の補正光学素子と、表示部とコンバイナと補正光学素子とが取り付けられ、固定具を介して車両に固定される被固定部と、を備え、補正光学素子が画像の拡大機能を有している。【選択図】図３
