PURPOSE: A luminous element array and a backlight unit including the same are provided to reduce manufacture costs by charging the inner side of a cavity with mold materials at a time and simplifying a manufacturing process. CONSTITUTION: A plurality of emitting devices(140) is mounted within a groove of a substrate. The plurality of emitting devices is electrically connected to a first metal layer(120). A cavity formation member is laminated on the substrate as a constant height. A second metal layer(150) is arranged in the lower side of the substrate. The second metal layer emits heat created from the emitting device. Mold materials(170) are charged within a cavity in order to cover the emitting device. A first reflective layer is formed on the second metal layer. A second reflective layer is formed on the inner wall of the cavity. |
