Abstract
A head-up display device adapted to project a first image beam and a second image beam onto a target element is provided. The head-up display device includes a display unit, a first optical module, and a second optical module. The first and the second image beams from the display unit are sequentially transmitted the first and the second optical modules. The first image beam and the second image beam are respectively reflected by the second optical module out of the head-up display, and then transmitted to the target element to form a first virtual image and a second virtual image. Through the first optical module, the optical path length of the first image beam from the display unit to the position of the first virtual image is greater than the optical path length of the second image beam from the display unit to the position of the second virtual image.
