1. A display device comprising:

  • a matrix of rows and columns of pixels;

    a group of first wires, each first wire coupled to a respective one of the rows of pixels;

    a group of second wires, each second wire coupled to a respective one of the columns of pixels;

    first voltage applying means for applying a scanning voltage to each of the first wires successively; and

    second voltage applying means for applying respective signal voltages to each of the second wires in synchronization with the scanning voltage successively applied to the first wires, characterized in that the display device further comprises a period changing means for changing a time period of applying the signal voltage in dependence on a distance between a row of pixels and the second voltage applying means.
