The invention provides a light source device and a head-up display which can be miniaturized and realize uniform illumination. The present invention is provided with: a first light source (11) and a second light source (12); irradiation units (14, 15) for irradiating the first emitted light emitted from the first light source (11) and the second emitted light emitted from the second light source (12); and at least one of a light-collecting part that is disposed between the first light source (11) and the irradiation parts (14, 15) and that collects the first emitted light, and a diffusion part (D1) that is disposed between the second light source (12) and the irradiation parts (14, 15) and that diffuses the second emitted light.
本发明提供一种能够小型化且实现均匀的照明的光源装置和平视显示器。其具备:第一光源(11)和第二光源(12);照射部(14、15),照射从第一光源(11)射出的第一射出光和从第二光源(12)射出的第二射出光;以及聚光部和扩散部(D1)中的至少一方,所述聚光部配置于第一光源(11)与照射部(14、15)之间,对第一射出光进行聚光,所述扩散部(D1)配置于第二光源(12)与照射部(14、15)之间,使第二射出光扩散。
