Abstract

The utility model provides a head-up display device. A head-up display device includes: a light source; a liquid crystal display panel (12A) that receives the illumination light from the light source and emits display light (L); and a light box (70) that holds the liquid crystal display panel (12A) in a state inclined with respect to the Z direction. The light box (70) is provided with: first abutting parts (73A, 73B) which are in contact with the liquid crystal display panel (12A); and first elastic parts (71A, 71B) having a contact surface (71s) that presses the liquid crystal display panel (12A) so as to press the liquid crystal display panel (12A) against the first abutting parts (73A, 73B). The first elastic sections (71A, 71B) are positioned on the end side of the liquid crystal display panel (12A), said end side being closer to the light source (11a), said end side being inclined with respect to the light traveling direction of the display light (L). The contact surface (71s) is formed as a light box (70) monomer so as to be exposed in the light traveling direction. According to the head-up display device, the assembling performance can be improved.
