A white light emitting device, and a backlight unit and an LCD device having the same are provided to enable a color mixing unit to contain plural LEDs for emitting RGB light respectively and to emit white light, thereby improving external badness caused by the deterioration of color mixing and improving brightness generated in the area of a brightness input part of a light guide panel. A white light emitting device includes at least one RGB(Red, Green, Blue) LEDs(150) and a color mixing unit(200). The color mixing unit has plural light emitting portions(201). The plural light emitting portions contain the LEDs and emit RGB light emitted from the LEDs in a mixed state. The plural light emitting portions are disposed at regular intervals in a side of the color mixing unit. The light emitting portions are formed greater than the light emitting surface of the LEDs. The number of the light emitting portions is provided more than the number of the LEDs. |
