BACKLIGHT DEVICE AND DISPLAY DEVICE USING SAME

摘要

A backlight device (3) is provided with a substrate (9) whereupon a plurality of light emitting diodes (10) are arranged, and a lower side chassis (heat dissipating section) (6) where heat generated in the light emitting diodes (10) is transferred from the substrate (9) and dissipated to the external. A heating value of each light emitting diode (10) is previously measured, and based on the measurement results of the heating values, an arrangement position on the substrate (9) is determined and corresponding light emitting diodes (10) are arranged.
