Abstract
A heads-up display device includes a display unit which outputs a 3D image and at least one holographic optical element which is attached to a windshield of the vehicle to diffract and reflect the 3D image output from the display unit so that a reflection efficiency of the 3D image may be improved while minimizing a module volume.
