Abstract:
1. A display device provided with a display element of an active matrix type comprising: scanning signal lines for supplying thereto scanning signals from a scanning signal driver; data signal lines for supplying thereto data signals from a data signal driver by AC driving; and pixels connected to said scanning signal lines and said data signal lines, each of said pixels including a predetermined electric capacitance in which a charge, which determines a display state as an active element is periodically set in a selection state, is written via the active element based on a scanning signal and a data signal, wherein said display element is arranged so as to suppress fluctuation in voltage due to a noise added to the voltage of the electric capacitance from the scanning signal line with a supply of the scanning signal to below a level at which flicker noise is perceptible in a display, said display device further comprising: frequency setting means capable of setting a rewriting frequency, which determines a cycle of writing the charge, to be not more than 30 Hz.
