Abstract
A liquid crystal display apparatus comprises a plurality of signal lines and scanning lines which are arranged so as to extend in directions orthogonal to each other and cross each other at cross portions, a plurality of pixel electrodes respectively provided at the cross portions so as to form a matrix arrangement, and a plurality of thin film transistors respectively provided between the pixel electrodes and the signal lines and respectively having gates connected with the scanning lines, for functioning as switches for writing image signals which are supplied from the signal lines into the pixel electrodes, picture change detecting means for detecting a change between still and moving pictures in a direction of time-axis included in a display image, and gate signal change means for changing the number of interlaced scanning lines in accordance with a change component detected in the picture change detecting means.
