摘要：
A planar illumination device is provided with a plurality of light guide paths, on which scanned light in different scanning sections of a scanning range by a scanning unit is respectively incident, and an illumination unit having a plurality of emission regions for emitting the light guided by the respective light guide paths. The number of the emission regions is 2 or more and 1000 or less, and the respective emission regions successively become luminous as the scanned light is incident on the respective light guide paths.
