Abstract
Occurrence of coloration at a screen end portion is suppressed when a backlight device having a configuration combining a blue LED and a wavelength conversion sheet is adopted. In a backlight device () adopting a configuration combining a blue LED () and a phosphor sheet () in order to obtain white light, a reflection partition () is provided on an LED substrate () so as to surround the blue LED () (more specifically, so as to surround an LED unit including one or a plurality of blue LEDs ()). A surface of the reflection partition () is formed of a reflection material. A height and an angle of the reflection partition () is designed so that light emitted from the blue LED () corresponding to each area does not reach other areas.
