Abstract
Object: To provide a backlight device for a liquid crystal display device which can suppress occurrence of power loss in any of light emitting bodies, and a liquid crystal display device including the backlight device. Solution to Problem: In a cluster (), arranged are two magenta light emitting bodies () including a blue light emitting element () with high drive voltage and red phosphors () covering the blue light emitting element (), two green light emitting bodies (), and one blue light emitting body (). With this configuration, since two blue LED elements () are implemented also in two magenta light emitting bodies (), the drive voltage of the magenta light emitting bodies () is substantially equal to the drive voltage of the green light emitting bodies () and the blue light emitting body ().
