摘要：A backlight unit and an LCD(Liquid Crystal Display) having the same are provided to prevent align faults of LEDs by having a light guide plate including receiving holes aligned in a form that the LEDs are inserted. A backlight unit(120) comprises the followings. Plural LEDs(Light Emitting Diodes)(150) emit light. A driving board(151) supplies power to the LEDs. A light guide plate(160) is disposed to make one side with the LED, and converts point light to surface light. A reflection sheet(170) is disposed in the rear of the light guide plate, and reflects light. Optical sheets(130) are disposed on the light guide plate, and diffuse and concentrate light. In an edge of one side of the light guide plate, at least one or more receiving holes(201) capable of being coupled with the at least one or more LEDs are formed.
