A head-up display includes illuminating device (110) and an optical reflection unit for reflecting light from illuminating device (110). Illuminating device (110) includes a plurality of light sources (111) arranged in a first direction and a plurality of first lenses (112) disposed corresponding to the plurality of light sources in an emitting direction of the plurality of light sources (111). Each of the plurality of first lenses (112) has first incidence plane (112a) and first emitting plane (112b), At least one of first incidence plane (112a) and first emitting plane (112b) is convex. Illuminating device (110) also includes second lens (113) disposed in an emitting direction of the plurality of first lenses (112) and diffusing plate (114) disposed in an emitting direction of second lens (113). Second lens (113) has second incidence plane (113a) and second emitting plane (113b). At least one of second incidence plane (113a) and second emitting plane (113b) has a concave cross-section in the first direction.
