ABSTRACT:
A side-light type backlight includes a light source having a plurality of LEDs and a light guide plate, where opposing end surfaces of the light guide plate define light incidence surfaces, with the plurality of LEDs being arranged at one of the light incidence surfaces. A number, M, of the LEDs are arranged in a longitudinal direction of the light incidence surface of the light guide plate, and are electrically connected such that there are a plurality of groups of the LEDs with each group having N LEDs mutually adjacently arranged in series. The groups are adjacently arranged in a longitudinal line, and at least one of the groups of LEDs is a separate parallel connection from an adjacent group of LEDs. The plurality of LEDs includes LEDs having a plurality of colors, and the LEDs arranged in series include LEDs having different colors.
