Title:
HEAD-UP DISPLAY DEVICE AND IMAGE PROJECTION UNIT
Document Type and Number:
WIPO Patent Application WO/2017/199627
Kind Code:
A1
Abstract:
This head-up display device is installed in a moving body (1) and displays a virtual image that can be seen by an occupant by projecting display light for the image onto a projection member (3). An illumination light source part (10, 210) generates illumination light. An image display panel (40) allows the illumination light from the illumination light source part to pass therethrough and emits the illumination light from a display surface (44) as the display light to display the image. A projection lens (30, 230, 330) is disposed between the illumination light source part and the image display panel, and projects the illumination light from the illumination light source part onto the image display panel. The image display panel is obliquely disposed in such a manner that the normal direction (ND) to the display surface intersects with the optical axis (OA) of the illumination light source part. The projection lens is obliquely disposed in such a manner that the radial direction (DD) of the projection lens matches the tangential direction (TD) of the display surface.
