ILLUMINATION DEVICE, AND DISPLAY DEVICE

WIPO Patent Application WO/2012/053411

A1

Provided are an illumination device and a display device, wherein it is possible to equalize the chromaticity of illumination light at the surface while preventing the light extraction efficiency from deteriorating. An optical modulation layer (34) which has transparency or exerts dispersibility with regard to light propagating through a light-guiding plate (10) is disposed on an optical modulation element (30) attached to the light-guiding plate (10). The optical modulation layer (34) is sandwiched between a pair of transparent substrates (31, 36). An alignment film (33, 35) for regulating the alignment of the optical modulation layer (34) is disposed on each surface of the transparent substrates (31, 36). However, electrodes (32) for generating an electric field for changing the alignment of the optical modulation layer (34) are only disposed on the surface of transparent substrate (31).
