Abstract
An illumination device including a plurality of illumination areas, each of which is individually controllable, includes a plurality of light-emitting devices disposed in a matrix pattern in each of the illumination areas where emission colors are disposed in a different manner between adjacent rows and between adjacent columns. Consequently, the emission of uneven luminance or uneven color is prevented from occurring in boundary portions of each of the illumination areas.
