Abstract
An illuminating device capable of improving display luminance while decreasing light leakage in a range with a large view angle and a display unit are provided. In a light modulation device bonded to a light guide plate, a light modulation layer containing a bulk and microparticles is provided. Both the bulk and the microparticles have optical anisotropy, and each response speed to an electric field is different from each other. Thereby, by controlling the electric field, each optical axis orientation of the bulk and the microparticles is able to correspond with each other, or is able to be different from each other.
