A display ON sequence for preventing problems in a display at the starting time of a liquid crystal display device is prevented from having malfunctions, which might otherwise be caused in a scanning line drive circuit by applying a voltage to scanning signal lines. In the display ON sequence at the starting time of the liquid crystal display device of an active matrix type, all the scanning signal lines of a liquid crystal panel are brought into a selected state thereby to release the electric charges in the liquid crystal capacity and the auxiliary capacity in each pixel forming portion through data signal lines. After this, the scanning signal lines are stepwise brought into an unselected state by dividing them several times, before their sequential selections (or scans) for the display are started. Thus, the electric current to flow through the bulk of the scanning signal line drive circuit is made lower than that of the prior art, in which the scanning signal lines were simultaneously brought into the unselected state.
