PURPOSE: A backlight unit is provided to prevent light loss from a light emitting diode by including a reflection portion in the backlight unit. CONSTITUTION: At least one LED(Light Emitting Diode)(220) is mounted in the upper part of a PCB[Printed Circuit Board](210). A reflection portion(230) includes at least one opening portion which corresponds to the LED. A side reflection portion(240) is extended from both side parts which correspond to the reflection portion. A light guide plate(250) is arranged in the upper part of the reflection portion and comprises an upper surface(251), a lower surface(252), and multiple side surfaces(253,254). |
