摘要：Problem to be solved: to provide a head up display device having a simplestructure and a small optical performance while being compact. A head up display device100 includesAn image formed by the display element 11 is projected by the projectionoptical system 15 to form an intermediate image I1 on the intermediate screen 16m.The

intermediate image I1 is displayed by a virtual image generating optical system 17.Avirtual image generating optical system 17 isHaving at least one free surface mirror17a;Intermediate screenIs a reflective surface having diffusion characteristics;When thevirtual image is perpendicular to the horizontal plane (virtual image I2 '), it is tiltedrelative to the conjugate plane at the position of the intermediate screen 16m'.Diagram
