HEAD-UP DISPLAY DEVICE

Provided is a head-up display device capable of reducing the divergence angle of display light which has passed a cross point. A head-up display device comprises: a light source that emits light beams; a liquid crystal panel that emits display light beams upon reception of the light beams from the light source; a first mirror that reflects the display light beams from the liquid crystal panel and causes the reflected display light beams to cross at a cross point in a crossing direction; a second mirror that reflects the display light beams reflected on the first mirror and passed through the cross point; and a second lenticular lens that converges the light beams from the light source and causes the display light beams to reach the first mirror in the converged state.
