To facilitate a gradation transition from the last gradation to a current gradation, in a modulation driving processing section for correcting current image data, the gradation transition is facilitated in such a degree that an actual luminance of the pixel can be a luminance indicated by image data of a current frame in a state where the gradation transition is made to a sufficient level from the second last gradation to the last gradation. In the liquid crystal display panel, d2·γ/ΔV is set to be not larger than 41×10−6 [mm4/(V·s)] wherein d [μm] indicates a thickness of the liquid crystal layer in the liquid crystal panel, γ[mm2/s] indicates a flow viscosity when the liquid crystal panel is set to a temperature of 5° C., and ΔV[V] indicates a difference in liquid crystal layer application voltage between a maximum luminance display and a minimum luminance display. With this structure, under general use conditions of the liquid crystal display apparatus, an improved response speed can be realized by facilitating a gradation transition from the last gradation to the current gradation by means of one parameter, and a high display quality can be maintained.
