description PROBLEM TO BE SOLVED: To provide a planar light source device and a liquid crystal display with controlled color and brightness unevenness etc. SOLUTION: The planar light source device includes a plurality of LEDs 1 disposed in a column. Of the plurality of LEDs 1, each of the LEDs 1 arranged in both ends in the direction of disposition is of lower brightness than the remaining LEDs 1. In addition, each of the plurality of LEDs 1 is subject to stabilized current control. In each of LEDs 1 in both the ends, is flown a current differing from the currents in remaining LEDs 1.
