摘要:
First aspect of the present invention: In dot inversion driving, polarities of image signals written to contiguous left and right ones of pixels differ from each other and accordingly, a domain is produced at corners of an opening portion, as a result, an aperture rate of the pixel is lowered and the transmittivity is deteriorated. In the case of an active matrix type TFT liquid crystal display apparatus of a dot successive driving system, gate lines Vg1 through Vg5 are wired to meander between the pixels of two upper and lower lines, Cs lines are wired in a matrix shape, image signals video1 and video2 having polarities inverse to each other are simultaneously written to the pixels of different upper and lower two lines and polarities of the pixels in a pixel arrangement after the writing operation are made the same polarity between contiguous left and right ones of the pixels and inverse polarities between upper and lower ones of the pixels.
