摘要： As each of sampling switch elements turns on in response to a scanning signal, a signal voltage from a signal wire is held on and written into a sampling capacitor. At this time, the signal voltage is held on the sampling capacitor on the basis of a common electrode. As the scanning signal transitions from high level to low level, each of the sampling switch elements turns off and changes into a floating state in which the sampling capacitor is electrically insulated from the signal wire and a driving TFT. As the scanning signal changes from high level to low level, each of the driving switches becomes conductive so that the signal voltage held on the sampling capacitor is applied as it is between the source and gate of the driving TFT as a bias voltage to make the driving TFT conductive, causing an organic LED to emit light.
