PROBLEM TO BE SOLVED: To provide a liquid crystal display capable of displaying high-quality moving pictures with a simple constitution and to provide a method for driving the display device. SOLUTION: A driving circuit 20 classifies a combination of a displayed gray-scale level of a previous vertical scanning period and a regular gray-scale level corresponding to an input image signal in a current vertical scanning period into either a first group or a second group. The combination is classified into the first group if a luminance reaches L<SB>1</SB>+(L<SB>2</SB>-L<SB>1</SB>)×C<SB>1</SB>(wherein L<SB>1</SB>is a luminance corresponding to the displayed gray-scale in the previous vertical scanning period, L<SB>2</SB>is a luminance corresponding to the regular gray-scale, and C<SB>1</SB>is a predetermined constant which is greater than 0 and equal to or less than 1) within a period corresponding to one vertical scanning period when a gray-scale voltage corresponding to the regular gray-scale is supplied, and otherwise classified into the second group. The driving circuit is capable of supplying the gray-scale voltage corresponding to the regular gray-scale level for any combination belonging to the first group, and supplying a gray-scale voltage (irregular gray-scale voltage) corresponding to an alternative gray-scale level (irregular gray-scale) which is different from the regular gray-scale level for any combination belonging to the second group.
