1. A display device comprising:

  • a pixel array having a plurality of pixels which are arranged two-dimensionally along the first direction and the second direction which crosses the first direction;

    a plurality of first signal lines which are juxtaposed along the second direction of the pixel array and transmit scanning signals which select a plurality of pixel rows consisting of respective groups formed of a plurality of pixels along the first direction;

    a plurality of second signal lines which are juxtaposed along the first direction of the pixel array and supply display signals to the pixels included in pixel rows which are selected from a plurality of pixel rows in response to scanning signals, the display signals determining respective display gray scales of the pixels;

    a first driving circuit which outputs the scanning signals to a plurality of respective first signal lines;

    a second driving circuit which outputs the display signals to a plurality of respective second signal lines; and

    a display control circuit which receives video data and control signals for every frame period, transmits a first clock signal which controls an outputting interval of the scanning signals from the first driving circuit and a scanning starting signal which instructs starting of the pixel row selection step in response to the first clock signal to the first driving circuit, and transmits display data which are served for generating display signals which are generated based on the video data and are outputted from the second driving circuit and a second clock signal which controls an outputting interval of the display signals from the second driving circuit, wherein the display control circuit makes the first driving circuit perform at least twice the pixel row selection step in the pixel array for every frame period in which the display device receives video data, and the second driving circuit outputs the display signals in response to the selection of respective pixel rows in the first pixel row selection step which is performed every frame period and outputs display signals which display the pixel array darker than the first selection step to respective selected pixel rows in the second selection step of the pixel row.
