Abstract
A driving method of the invention is suitable for an active matrix type liquid crystal display apparatus having row and column electrodes. The driving method includes the steps of applying a gate-one pulse for writing data for one line to the column electrodes to each of the row electrodes. The gate-on pulse has a pulse waveform which includes at least one concave portion during a horizontal period.
