A head up display device includes a pancake lens and a picture generation unit. The pancake lens includes a half mirror and a reflective polarizer. The half mirror has a light incident surface and a reflective surface. The reflective polarizer is disposed on the reflective surface and combined with the half mirror for forming a reflective space. The picture generation unit is disposed in the direction of the pancake lens opposite to the user's eyes. The picture generation unit generates image light and the image light enters the reflective space from the light incident surface. After the reflection, the image light is directed towards the user's eyes to form a virtual image. The optical path of the virtual image and the image light has a un-axis angle.
A head up display device, comprising:
a pancake lens, the pancake lens includes a half mirror and a reflective polarizer, wherein the half mirror includes a light incident surface and a reflective surface, the reflective polarizer being disposed on the reflective surface and being combined with the half mirror to form a reflective space;
a picture generation unit, disposed on a direction of the pancake lens opposite to the user's eyes, the picture generation unit generates an image light which enters the reflective space through the light incident surface, after reflection, a virtual image is formed towards the user's eyes through the reflective polarizer, wherein optical paths of the virtual image and the image light have an un-axis angle.
