A directly illuminated display unit has a light source unit that includes one or more light sources capable of producing illumination light for illuminating a display panel. A diffuser layer is disposed between the light source unit and the display panel. At least one of a first brightness enhancing layer and a reflective polarizer is disposed between the diffuser layer and the display panel. A light-diverting surface is disposed between the diffuser layer and the light source unit. The light-diverting surface diverts a propagation direction of at least some of the illumination light passing from the light source unit to the diffuser layer.
