the LEDs (19). The substrates (18) is separated corresponding to a plurality
of areas (22) formed by dividing an area where all LEDs (19) are disposed, and the
LEDs (19) are grouped corresponding to respective areas (22) and substrates
(18). Grouped LEDs (19) are respectively lit by the light- controllable lighting
circuits (20) different from each other. The LED (19) near the boundary of one
