ABSTRACT:
A back light for a liquid crystal display (LCD) includes a mold part. A first lead frame is installed on the inside of the mold part. In the first lead frame, the light emitting diodes are uniformly spaced apart from one another and each light emitting diode includes a chip. A first electrode is formed on one side of the chip and attached to the first lead frame. A second electrode is divided into two parts and formed on the other side of the chip. A plurality of conducting layers are respectively disposed between the light emitting diodes and each conducting layer is attached to the first lead frame. A plurality of connecting members connect each second electrode with each adjacent conducting layer. A second lead frame is installed on the inside of the mold part to be adjacent to the first lead frame. The second lead frame is connected to the adjacent second electrode by one of the connecting members.
