Abstract
In a direct backlight, a substrate on which LEDs are provided includes a plurality of module substrates. Each module substrate can be reduced in warping or deformation after a blanking process. In addition, each module substrate can be formed thin since bending due to its own weight is small. Consequently, the substrate as a whole and the backlight can be formed thin.
