description PURPOSE: A head up display device of a vehicle and a method thereof are provided to be applied on a front window of a large vehicle by implementing a technology of displaying vehicle traveling information on the front window of a vehicle. CONSTITUTION: A backlight part(110) generates an illumination light. A liquid crystal panel(120) outputs traveling information on a front window of a vehicle forming a vertical angle more than 70°, using the illumination light as a light source. A first optical lens(130) is located in front of the liquid crystal panel, and smoothens the image of the outputted traveling information and focuses the image to one spot in the front. A first reflection mirror(140) is located at the one front spot of the first optical lens, and reflects the focused image of traveling information to one side direction. A second optical lens(150) enlarges the size of the reflected image to a half size of the image formed on the front window. A third optical lens(160) enlarges an output image of the second optical lens to have a rated size on the front window. A second reflection mirror(170) reflects an output image of the third optical lens toward the front window in order for the image of traveling information to be displayed on the front window.
