Abstract:
In one embodiment of the present invention, a liquid crystal display device is disclosed, each pixel includes first and second subpixels, each of which includes a storage capacitor. Storage capacitor counter voltages applied independently to the storage capacitor counter electrodes of the first and second subpixels are varied within each vertical scanning period of the input video signal. As a result, each vertical scanning period of the input video signal includes a first subframe in which the first and second subpixels have luminances Y_SP1_A and Y_SP2_A, respectively, and a second subframe SFB in which the first and second subpixels have luminances Y_SP1_B and Y_SP2_B, respectively, where Y_SP1_A≠Y_SP2_A, Y_SP1_B≠Y_SP2_B, and Y_SP1_A≠Y_SP1_B or Y_SP2_A≠Y_SP2_B are satisfied. As a result, the viewing angle dependence of the γ characteristic can be reduced with the decrease in the transmittance of the liquid crystal display device minimized.
