A display device includes a pixel array having a plurality of pixels, a plurality of first signal lines and a plurality of second signal lines. A first driving circuit outputs scanning signals to the plurality of first signal lines, and a second driving circuit outputs display signals to the plurality of second signal lines. Each pixel of the plurality of pixels is operated in a normally black-displaying mode, the first driving circuit repeats a first step of sequentially selecting N lines of the plurality of first signal lines and a second step of selecting Z lines of the plurality of first signal lines that are separate from the N lines, where N and Z are natural numbers, and the second driving circuit repeats outputting N times the display signals and outputting one time a blanking signal which masks an image displayed on corresponding pixels.
