Abstract
The present invention comprises: a display unit having a plurality of pixels arranged therein, each pixel including an organic EL element 24, a switching TFT, and a drive TFT; a data signal drive circuit for receiving image data for each frame period and outputting an image signal based on the image data; a scanning signal drive circuit for outputting a scanning signal for controlling a timing at which the switching element of each of the plurality of pixels receives the image signal; and a current source (a light emission power supply unit and a cathode potential control circuit together) for outputting a current supplied to the light emitting unit of each of the plurality of pixels through its drive element; wherein the current source modulates the value of the output current within each frame period.
