A display device which effectively reduces the occurrences of a false contour is provided. A driver digitally drives each pixel by obtaining a plurality of bit data from pixel data for one pixel to assign the plurality of bit data to a corresponding subframe; configuring one frame with a predetermined number of unit frames; and supplying corresponding bit data in each unit frame to each pixel. Specifically, an analyzing circuit 5-5 predicts a probability of occurrence of a false contour in one screen of the video signal based on the presence or absence of a true contour. A display method based on the video signal is set in accordance with an analysis result.
