PROBLEM TO BE SOLVED: To reduce display unevenness of a display device using current-driven type light emitting elements. SOLUTION: As a current driving device, it is provided with a 1st integrated circuit and a 2nd integrated circuit. The 1st integrated circuit comprises a current mirror circuit which produces a reference current according to a standard current and outputs the current to the 2nd integrated circuit via a reference current transmission line, and a 1st current driving circuit which produces a current for driving current-driven elements and outputs the current thereto. The 2nd integrated circuit comprises a current mirror part which produces a feedback current according to the reference current and outputs the current to the 1st integrated circuit via a feedback current transmission line, and also produces and outputs a driving circuit current according to the reference current, and a 2nd current driving circuit which receives the driving circuit current as an input via an external resistor having a resistance value almost equal to that of the feedback current transmission line, and which produces and outputs a current for driving the current-driven type elements based on the driving circuit current. |
