This head-up display device according to an embodiment of the present invention is mounted on an instrument panel of a vehicle. A display means that emits display light is contained in a chassis having a light transmissive cover having a curved surface, and the display light emitted by the display means is output from the light transmissive cover. The curved surface of the light transmissive cover is curved so that the side on the front side of the vehicle is lower than the side on the back side of the vehicle, and that the curved surface is inclined toward the left-right direction of the vehicle so that a corner of the curved surface is lowest.
The problem addressed by the present invention is to provide a head up display device capable of counteracting sunlight without using a shutter or a reflection type polarizing film. A first concave mirror has a curvature to cause the reflected display light to intersect vertically before reaching a second mirror, and a second concave mirror serves to reflect the received display light. A case is provided with a first shield and a second shield extending near an intersecting point to sandwich a light path between the first and second concave mirrors. The first and second shields can block external light entering into the case from outside the case and proceeding toward the first concave mirror after being reflected from the second concave mirror.
The present invention is compact and inexpensive, has good light efficiency, and enables a display image having a plurality of display distances to be displayed. A display emits projection light for displaying a display image at a predetermined position, and an image formation position adjusting mirror receives the projection light emitted from the display, performs conversion into a plurality of first projection light and second projection light that have different image formation distances by changing the image formation distance of the projection light that is at least part of the incident projection light, and reflects the first projection light and the second projection light to project the first projection light and the second projection light onto a first screen and a second screen.
The purpose of the present invention is to efficiently orient image light toward an observer. A display device outputs projection light for displaying an image. A transmission type screen forms an image of the projection light and diffuses the same as image light. A projection lens enlarges projection light and forms the image on the transmission type screen. A light distribution adjustment means is disposed between the transmission type screen and the projection lens and adjusts the light distribution of the image light output by the transmission type screen for each region by refracting the projection light.
