A video image display device is provided. The device includes an expansion factor deriving unit deriving and outputting an expansion factor for each frame of the video image data, for use in a luminance range expansion process for expanding a luminance range of the video image data on the basis of an image characterizing quantity related to the luminance of the video image data corresponding to the frame; a luminance range expansion processing unit performing the luminance range expansion process to the video image data on the basis of the expansion factor output from the expansion factor deriving unit; and a scene-change detecting unit detecting a change in a screen state of a present frame into a black screen state on the basis of the video image data and detecting a scene-change indicating that the scene of the video image has changed.
