Active-matrix display device, and active-matrix organic electroluminescent display device

A display device comprising:

• a pixel element for emitting light according to a current signal,
• a current line for supplying the current signal to the pixel element,
• a driving circuit including a holding unit, the holding unit including a capacitor that holds luminance data of image information, and a first transistor that supplies the current signal to the current line according to the luminance data held in the holding unit, wherein
• the image information is written to the holding unit through a second transistor as a voltage signal,
• the first transistor transforms the luminance data stored in the voltage signal into the current signal to be supplied to the pixel element, and
• the driving circuit further comprises a third transistor and a fourth transistor connected to the first transistor, and a fifth transistor connected to the holding unit, wherein
• the third transistor switches current flow on and off from the first transistor to the current line,
• the fourth transistor electrically connects a current node of the first transistor to a gate node of the first transistor, the fifth transistor writes a reset voltage to the holding unit, and the luminance data of the image information is written to the holding unit during a predetermined period, and
• the third transistor is in an off state in at least a portion of the predetermined period.
