    摘要： A color display pixel P CD in a liquid crystal display device ( 100 ) includes first through fourth pixels P 1 through P 4 arrayed in two rows by two columns, and first and second signal lines ( 13a, 13b ) which are located in correspondence with each column of pixels and are supplied with signal voltages of polarities opposite to each other from a signal line driving circuit ( 30 ) in each vertical scanning period. A TFT ( 14 ) of one of the first and third pixel P 1 and P 3 is connected to the first signal line ( 13a ), and a TFT ( 14 ) of the other pixel is connected to the second signal line (1 3 b). A TFT ( 14 ) of one of the second and fourth pixel P 2 and P 4 is connected to the first signal line ( 13a ), and a TFT ( 14 ) of the other pixel is connected to the second signal line ( 13b ). The TFTs ( 14 ) of the first through fourth pixels P 1 through P 4 are controlled to be ON/OFF by a common scanning signal, and the polarities of the signal voltages supplied to the first and second signal lines ( 13a, 13b ) are constant during an arbitrary vertical scanning period. Owing to this, the load on the signal line driving circuit is reduced.

    摘要： A stereoscopic video image display method according to the present invention is such that in a case where switching between a right-eye image and a left-eye image, both of which accommodate a parallax that allows an observer to visually recognize a stereoscopic video image, is done once, for example, every two frames, a gray scale transition emphasis process is carried out in each of the frames, and that in a case where, in a visual recognition period (e.g. frame F2) during which the observer is allowed to visually recognize a stereoscopic video image, display luminance of a target pixel which belongs to a parallax region is made transition from display luminance corresponding to 160 gray scale to display luminance corresponding to 32 gray scale, a gray scale transition emphasis process is carried out so that an average luminance during the visual recognition period becomes substantially equal to the display luminance corresponding to 32 gray scale.
