Abstract

An illumination unit including one or more light sources each including a solid-state light-emitting device; and an optical member configured to allow light incident from the solid-state light-emitting device to pass therethrough and exit therefrom, and at least one of the chips in the one or more light sources is configured of a laser diode. The optical member includes an integrator including a first fly-eye lens on which light from the solid-state light-emitting device is incident. A major-axis direction of a luminance distribution shape of light incident on an incident plane of the first fly-eye lens is different from arrangement directions of the cells in the first fly-eye lens.
