1. A display device of an electric current driving type, comprising:

  • a plurality of pixel circuits arranged in correspondence with intersections of a plurality of scanning lines and a plurality of data lines, each pixel circuit including an electro-optical element and a drive element having a control terminal connected to the data line through a switching element;

    a scanning signal output circuit selecting a write-target pixel circuit through use of the scanning line, and exercising control such that the selected pixel circuit outputs, to the data line, a voltage which depends on a threshold voltage of the drive element; and

    a display signal output circuit applying, to the data line, a voltage obtained by adding or subtracting a correction voltage corresponding to the threshold voltage to or from a data voltage corresponding to display data, based on the voltage outputted to the data line.
