ILLUMINATION DEVICE, DISPLAY DEVICE AND THREE-DIMENSIONAL DISPLAY DEVICE

摘要

In a scan system, a lighting unit, a display, and a three-dimensional display that have all of high luminance, low power consumption, and high reliability of a circuit board are provided. A light modulation device 30 bonded to a light guide plate 10 is provided with a light modulation layer 34 exhibiting scattering property or transparency to light propagating through the light guide plate 10. The light modulation layer 34 is interposed between a lower electrode 32 that is configured of a plurality of partial electrodes 32A extending in a direction parallel to a light incident surface 10A and a sheet-like upper electrode 36. A drive circuit 50 sequentially drives the plurality of partial electrodes 32A to scan a region exhibiting the scattering property of the light modulation layer 34 in a direction orthogonal to the light incident surface 10A.
