摘要： A liquid crystal display device of at least one embodiment of the present invention includes a TN-mode liquid crystal display panel which is constituted by pixels of three colors (red, green, and blue) and a color filter. A thickness of a liquid crystal layer (cell thickness) is determined on a basis of a retardation value of green light or red light, which has a larger wavelength than blue having shortest wavelength among the three colors. A display data switching circuit carries out gradation conversion of shifting input gradation values to lower gradation values with respect to image data supplied to pixels of blue. Thus, grayscale inversion is prevented. The liquid crystal display device of the present invention produces an effect of improving transmittance of pixels of colors having wavelengths other than the wavelength of blue.

摘要： In one embodiment of the present application, a liquid crystal panel drive device includes a signal processing section for determining an output gray scale in accordance with a gray scale transition from the gray scale which is forecasted to reach by a previous response to an input gray scale and can carry out overdrive with the output gray scale. At a temperature at which a rise gray scale transition may occur in absence of a response condition does not exist for single overdrive, the signal processing section determines, as an output gray scale, a gray scale lower than a maximum gray scale with respect to a particular gray scale transition out of a rise type gray scale transition. In such a way, a display quality (especially a moving image display quality) at a low temperature can be improved.
