Abstract
The present invention implements a more compact head-up display device and improves mountability on a vehicle. A first mirror causes first display light generating an upper end of a virtual image display plane to intersect with second display light generating a lower end of the virtual image display plane between the first mirror and a second mirror. The first mirror is formed such that the width of a first reflection area for reflecting the first display light is shorter than the width of a second reflection area for reflecting the second display light. The second mirror is formed such that the width of a third reflection area for reflecting the first display light is shorter than the width of a fourth reflection area for reflecting the second display light.
