Abstract
Provided is an edge light illumination device, in which a light modulation layer includes: a first region having optical anisotropy and a relatively high responsiveness to an electrical field; and a second region having optical anisotropy and a relatively low responsiveness to the electrical field. When denoting dispersal, the light modulation layer satisfies the formulae A>B>C and A1/C1<A2/C2.
