A data driver of an LCD(Liquid Crystal Display) device is provided to simplify a latch circuit by applying red, green, and blue data to a digital/analog converter through a shared output line. A data driver of an LCD(Liquid Crystal Display) device includes red, green, and blue color latches(32R,32G,32B), switches(SW_R,SW_G,SW_B), and common line, and a digital/analog converter(33). The red, green, and blue color latches latch red, green, and blue color data received sequentially from outside. The switches and common line deliver data outputted from the red, green, and blue color latches to the digital/analog converter. The digital/analog converter converts the data received through the common line into analog signals and outputs the converted signals to a line selector(34).
