Abstract: A backlight unit includes a printed circuit board; a light source on the printed circuit board; a light guide plate that receives light emitted from the light source on one surface and directs light outwards through another surface; and a light blocking unit between the light source and the light guide plate. The light blocking unit may be spaced apart from the light guide plate.

Abstract: A light emitting diode package includes a light emitting diode which emits a first light having a first color; a body member defining a planar part thereof on which the light emitting diode is mounted, and a side part thereof which is extended upward from the planar part, the planar and side parts defining an inner cavity in which the light emitting diode is disposed; and a filling member which fills the inner cavity and includes a base part in which a plurality of first phosphors is dispersed, the plurality of first phosphors absorbing a portion of the first light and generating a second light having a second color different from the first color. The body member which defines the planar and side parts thereof has a third color different color from the second color, and the body member having the third color absorbs light having the second color.

Abstract: A backlight unit including a bottom cover having a bottom surface and a sidewall extending from the bottom surface, light sources, and a reflection sheet. Outermost ones of the light sources are configured to include a first light source and a second light source. The first light source and the second light source have different distances from the sidewall. The reflection sheet includes a first reflection sheet disposed between the sidewall and the first light source and a second reflection sheet disposed between the sidewall and the second light source. The first reflection sheet and the second reflection sheet have different inclined angles from each other.
