An LCD(Liquid Crystal Display) is provided to arrange a metal PCB(Printed Circuit Board) with LED(Light Emitting Diode)s of an RGB array to a cardinal number row and to arrange a metal PCB with LEDs of a series of W(White) array to an ordinal number row. An LCD panel implements an image. A signal applying member produces a control signal for driving the LCD panel. A back light device(330) supplies the light beam to the LCD panel and drives at least one between the first group of light emitting member arrayed by red, green and blue and the second group of light emitting member arrayed by white. A back light driving member receives the control signal from the signal applying member and outputs at least one power for driving the first and second groups of light emitting members. The signal applying member includes a data driving member for supplying data to a data line of the LCD panel. A gate driving member supplies a gate pulse to a gate line of the LCD panel. A timing controller(310) receives R,G,B data from the outside, compares the color difference and brightness information and produces a control signal for selecting the light emitting member. |
