Abstract:
1. A liquid crystal display device dividing one frame into green, red and blue sub-frames, comprising: a plurality of data lines and a plurality of gate lines defining a plurality of liquid crystal cells; a data driver for sequentially supplying a green data signal during the green sub-frame, a red data signal during the red sub-frame and a blue data signal during the blue sub-frame to the data lines; a gate driver for applying a scanning pulse to the gate lines; and a light source for irradiating a green light onto the liquid crystal cells during the green sub-frame after the green data signal is maintained at the liquid crystal cells, irradiating a red light onto the liquid crystal cells during the red sub-frame after the red data signal is maintained at the liquid crystal cells, and irradiating a blue light to the liquid crystal cells during the blue sub-frame after the blue data signal is maintained at the liquid crystal cells, wherein the light transmittance of the liquid crystal cells at the later sub-frame has a value incorporating the cumulative light transmittance of the liquid crystal cells at the prior sub-frame.
