Image display device (120) is used in a head-up display. Image display device (120) includes an illumination unit, light guide plate (112), light beam controller (114), and display unit (115). The illumination unit includes a plurality of light sources (111). Light guide plate (112) includes incident surface (1121) into which light from the illumination unit enters, incident surface (1121) including a plurality of convex surfaces (112b) each of which is opposed to each of the plurality of light sources (111), and output surface (1123) disposed in a direction intersecting incident surface (1121) and from which the light incident from incident surface (1121) is output. Light beam controller (114) controls a traveling direction of the light output from output surface (1123). Display unit (115) transmits the light output from light beam controller (114) to display an image.
