Abstract
The present invention provides a liquid crystal display apparatus capable of reducing waving and shadowing. The driving circuit portion in the liquid crystal display apparatus according to the present invention has a random number generating circuit a display data RAM a display data RAM address decoder and a row driver The random number generating circuit generates random numbers for setting the scanning order of the row electrodes. The row address decoder sets the scanning order on the row electrodes. The column driver supplies the video data of all the column electrodes corresponding to the scanning row electrode. The scanning order of the scanning lines is set by the random numbers generated by the random number generating circuit Because of this, the scanning order becomes random at each frame, and the shadowing depending to the video data is reduced. Furthermore, because the adjacent scanning lines are not continuously scanned, the waving does not arise.
