Abstract
It is an object of the present invention to provide a display device where power consumption can be suppressed and the number of gray scales can be increased without a scanning line driver circuit on both sides of a pixel portion. In a display device having a scanning line driver circuit, a shift register included in the scanning line driver circuit has 4m-stage (m is a natural number) flip-flop circuits in every m scanning lines, and a signal which selects the scanning line in a first half period of one scanning line selection period and a signal which selects the scanning line in a second half period of the one scanning line selection period are output to the scanning line by another start pulse.
