Method for driving a liquid crystal display device and a liquid crystal display device
2007
The liquid crystal display device of the present invention (10) is provided with a red (R) · green (G) · blue liquid crystal display panel of three-color pixel and the TN mode is composed of color filters of the (B) (11) there. Based on the retardation value of light of the three colors is the shortest wavelength blue (B) large green wavelength than of (G) or red (R), the thickness of the liquid crystal layer (cell thickness) is determined that. Display data switching circuit (23), to the image data supplied to pixels of blue (B), performs gradation conversion to shift to a lower side of the gradation value than the value the input gradation value it allows to prevent gradation inversion. The liquid crystal display device of the present invention has an effect of improving the transmittance of the color of a pixel having a wavelength other than blue (B).
