Patent ID: 7887225

Claim:
A direct-type backlight unit comprising: a board having upper and lower surfaces defining a thickness therebetween; and a plurality of unit light sources mounted on the board, wherein each of the unit light sources comprises: a wiring pattern formed on the board; and a light emitting device disposed on the wiring pattern to electrically connect thereto; a non-conductive side wall surrounding, without interruption, the light emitting device at a predetermined interval therefrom, the non-conductive side wall having a height lower than that of the light emitting device; an encapsulant formed in a dome shape inside the side wall, the encapsulant comprising a transparent resin or a phosphor-mixed transparent resin; and an opaque layer or a light diffusing layer formed on an upper end portion of the encapsulant, bounded by an area corresponding to the light emitting device, located in a vertical upward direction of the light emitting device and blocks light generated from the light emitting device from traveling in an upward direction to prevent a bright light spot from forming, wherein the non-conductive side wall has a ring shaped structure with a through hole formed inside thereof and blocks a resin dispensed inside the non-conductive side wall from spreading out to form the dome shaped encapsulant.
