1. A backlight device for a liquid crystal display, comprising:

  • a light-guiding plate disposed at a rear of a liquid crystal display panel of the liquid crystal display;

    a first light source for emitting light along at least one side of the light-guiding plate, the first light source having a first sequential arrangement of green, blue, and green light emitting diodes along a first row direction, and at least one white light emitting diode at one end of the first sequential arrangement of the green, blue, and green light emitting diodes;

    a second light source for emitting light along the at least one side of the light-guiding plate, the second light source having a second sequential arrangement of blue, green, and red light emitting diodes along a second row direction different from the first row direction, and at least one white light emitting diode at one end of the second sequential arrangement of the blue, green, and red light emitting diodes;

    a housing adjacent to the light-guiding plate affixing the first and second light sources and concentrating the light emitted from the first and second light sources along a first light direction; and

    a reflecting plate disposed at a lower portion of the light-guiding plate forreflecting light leaking along a side of the liquid crystal display panel.
