Patent ID: 8581821

Claim:
A liquid crystal display device, comprising: display means including liquid crystal display elements corresponding to pixels which have a multi-pixel structure and which are arranged in matrix; first driving means for driving scanning lines connected to the liquid crystal display elements corresponding to the pixels; second driving means for driving signal lines connected to the liquid crystal display elements corresponding to the pixels; image acquisition means for acquiring an image signal to be displayed on the display means; and control means for controlling the first driving means and the second driving means in accordance with the image signal acquired by the image acquisition means, wherein, in the display means, each of the pixels, which has the multi-pixel structure and which is constituted by a first pixel and a second pixel, is connected to two corresponding signal lines, and first pixels and second pixels of pixels are connected to two corresponding signal lines in a checkerboard manner, the control means controls the first driving means in such a manner that all horizontal scanning lines of one frame are scanned by repeatedly scanning a first sub-frame in which only odd lines of horizontal scanning lines are scanned and a second sub-frame in which only even lines of horizontal scanning lines are scanned, and controls the second driving means in such a manner that the polarity of the first pixel of each of the pixels connected to the two corresponding signal lines differs from the polarity of the second pixel of the pixel, the polarities of the first pixels of adjacent pixels differ from each other, the polarities of the second pixels of adjacent pixels differ from each other, and a polarity signal is inverted when switching is performed between the first sub-frame and the second sub-frame, the control means divides all horizontal scanning lines of the display means into a plurality of areas constituted by four lines or more, and controls the first driving means in such a manner that all horizontal scanning lines of one frame are scanned by executing scanning of the first sub-frame and the second sub-frame in the plurality of areas, the control means sets a time period for performing an operation of writing at the first horizontal scanning line after switching is performed between the first sub-frame and the second sub-frame, to be longer than a time period for performing the operation of writing at another horizontal scanning line, and the first driving means and second driving means drive the liquid crystal display elements by a method other than dot inversion.
