PURPOSE: A control device for a color LCD(Liquid Crystal Display) is provided to maintain a color capable of being reproduced by an LCD and correct a gamma and a color temperature by subdividing an LUT(Look Up Table) for input RGB data and finely adjusting a driving voltage of an LCD panel. CONSTITUTION: An LUT unit(30a) receives color data(R,G,B) with N bits inputted from the outside, and outputs color data(R',G',B') with (N+k) bits converted using a predetermined LUT. A digital/analog converting unit(30b) receives the color data(R',G',B') with (N+k) bits outputted from the LUT unit, and outputs an analog voltage in proportion to a 2N+k level to an LCD panel(20).
