PURPOSE: A backlight unit including a light emitting diodes is provided to constantly maintain a pitch. CONSTITUTION: A backlight unit(100) includes as follows. A module substrate(136) includes a conductive layer(135) which has a circuit pattern. A light emitting module(130) includes a light emitting diode(140) which is mounted on the conductive layer. A connecting unit(150) is inserted to a connecting hole(151) which is separated to a predetermined distance form the conductive layer and is formed inside the module substrate. The connecting unit is a screw that has a screw line(153) in circumference of a connecting hole. |
