Zusammenfassung:	Disclosed is a method of driving a display panel for displaying a halftone image of each of fields constituting a video signal, each field being composed of a plurality of subfields. This method detects a luminance distribution of the video signal, divides each of the fields into a first subfield group comprised of N subfields and a second subfield group comprised of M subfields (N, M are integers equal to or more than one), and displays the first subfield group with 2N gradation levels and the second subfield group with (M+1) gradation levels. The numbers N, M of subfields respectively allocated to the first and second subfield groups are set in accordance with the luminance distribution.
