Abstract: Provided is a liquid crystal display device capable of independently adjusting gradation for each of RGB. A control circuit outputs a clock signal, an image signal for each of RGB, and an adding circuit control signal. A gradation voltage generation circuit outputs a gradation voltage. A color correction voltage for each of RGB is generated in a color correction voltage generation circuit based on an input signal for color correction. A signal electrode drive circuit receives the clock signal, a control signal, the image signal, the adding circuit control signal, the gradation voltage, and the color correction voltage. A gradation voltage corresponding to a gradation value of the image signal for each of RGB is selected from the gradation voltage. The color correction voltage for each of RGB is added to the gradation voltage, then a sub-pixel data signal is generated and sent to a liquid crystal panel.
