1. A light-emitting device comprising:

  • a plurality of pixels formed over a substrate, each of the plurality of pixels including n×

    m memory circuits for storing n-bit digital image signals for m frame periods, wherein the n is a natural number of 2 or more, and the m is 2;

    n latch circuits in one column;

    n source signal lines in the one column, each electrically connected to each of the n latch circuits; and

    one writing gate signal line in one of the plurality of pixels, electrically connected to gates of n writing transistors,wherein periods for emitting light from the plurality of pixels in one frame period among the m frame periods are divided to 2(n−

    1)
    , 2(n−

    2)
    , . . . , 20 with the n-bit digital image signals, andwherein a gradation of the light-emitting device is configured to be expressed by combining the periods in the one frame period.
