摘要： According to one embodiment, an illumination device includes a light guide plate and a plurality of light sources. The light guide plate includes a light emitting surface. The plurality of light sources whose light emission luminance can be controlled individually, the light sources being configured to supply light from an edge portion of the light guide plate into the light guide plate. A luminance distribution of light injected from the light sources into the light guide plate and emitted from the light emitting surface is obtained by a function such that relative intensity relative to a DC component in a spatial frequency region is less than or equal to a first threshold in a spatial frequency region having a value of one or more. Source-to-source distance of the light sources is optimized by the luminance distribution of the light.
