ABSTRACT:
Disclosed are a backlight unit capable of determining a deviated degree of a lamp grip by a guide line formed adjacent to the lamp grip a PCB that connects an electrode thereof with a lamp electrode, and a manufacturing method for the same. The manufacturing method includes preparing a case structure, a plurality of lamps equipped with an electrode at both ends, and fastening units corresponded to the electrodes of the lamps, preparing a PCB constituted by a base substrate and a signal line formed on the base substrate, and defined with positions thereon for forming the fastening units having electric connection parts with respect to the signal line, and positioning the PCB in the case structure, forming a solder layer at the electric connection parts on the PCB by applying a soldering material using a solder mask, and forming a guide pattern at both sides of the fastening unit, connecting the fastening units with the solder layers while using the guide patterns as marks, and connecting the lamps to the fastening units.
