Abstract
An illumination unit capable of obtaining high luminance and a display apparatus including it are provided. The illumination unit includes an illumination optical system generating the illumination light, and a lens sheet narrowing a divergence angle of the illumination light. The illumination optical system includes a first transparent substrate and a second transparent substrate that are separated from each other and are arranged to face each other, and a light source applying light to an end face of the first transparent substrate or of the second transparent substrate. The illumination optical system is provided in a gap between the first transparent substrate and the second transparent substrate, and includes a light modulation layer exhibiting scattering characteristics or transparent characteristics with respect to the light from the light source in accordance with a magnitude of an electric field. The illumination optical system includes an electrode generating an electric field that generates a plurality of linear scattering regions in the light modulation layer in a three-dimensional display mode, and generating an electric filed that generates a planar scattering region in the light modulation layer in a two-dimensional display mode.
