Abstract
A backlight device (10) includes: an LED package (12) including an LED chip (12A) and an Ag reflective layer (12B); and an optical member (for example, a prism sheet (16)) for adjusting light emitted from the LED package (12). The optical member (16) adjusts an amount of a halogen thus contained and the like so that emission of halogen is decreased to a degree in which no silver halide is generated on the Ag reflective layer (12B).
