Abstract
The backlight device includes a plurality of packages, and a light guide plate. The package includes a housing for package, and a plurality of light sources. The housing for package includes a tubular part having a wall surrounding the circumference, a bottom wall provided at one end of the tubular part, and a passing part provided at the other end of the tubular part for passing the light from inside to outside of the tubular part. The plurality of light sources are contained in the housing for package and disposed in the bottom wall, and emit light. The plurality of packages are arrayed in one direction. At least part of the layout of light sources relative to the incident plane is different from mutually adjacent packages.
Claims8
