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.

摘要： The liquid crystal display device of the invention includes: a liquid crystal layer taking on a roughly vertically aligned state in the black display state: first and second polarizing plates placed to face each other so that the transmission axes are orthogonal to each other; at least one first phase plate placed between the liquid crystal layer and the first polarizing plate and/or the second polarizing plate; at least one second phase plate placed between the first phase plate and the first or second polarizing plate whichever is farther from the first phase plate; and an illuminator for illuminating the liquid crystal layer with light via the first or second polarizing plate. The first phase plate has biaxial optical anisotropy and has functions of compensating part of thickness-direction retardation of the liquid crystal layer in the black display state and suppressing light leakage caused by deviation of the transmission axes of the first and second polarizing plates from the mutual orthogonal relationship in a tilted viewing angle direction. The second phase plate has negative uniaxial optical anisotropy and has a function of compensating the thickness-direction retardation of the liquid crystal layer in the black display state in cooperation with the first phase plate.

摘要： A modulation processing section compares video data of a current frame and a previous frame representative value supplied from a frame memory, corrects the video data so that a gradation transition from a gradation indicated by the previous frame representative value to a gradation indicated by the video data is emphasized, and outputs the corrected video data. A judgment section compares both of the data and judges, out of a value calculated from the previous frame representative value by a representative value generating section and the video data, which is to be stored in the frame memory till a next frame begins. This allows for realizing a liquid crystal display device capable of preventing with a relatively small-scale circuit (alternatively, a relatively small amount of calculation) a phenomenon such that: although a response speed of a pixel is improved, the emphasis modulation and a response delay of the pixel are combined so that image quality in displaying moving images deteriorates.
