摘要： An organic EL displaying apparatus which suppresses a defective display caused by a leak current at a time when an emission period controlling transistor is off is provided. The organic EL displaying apparatus comprises a plurality of pixels each of which includes an organic EL element, a power supply line, a driving transistor and the emission period controlling transistor, a data line, and a control line. In this apparatus, in a certain one of the pixels, a resistance Roff—ILM between source and drain electrodes of the emission period controlling transistor in an off state of the emission period controlling transistor, and a resistance Rbk—Dr between source and drain electrodes of the driving transistor in a state that a minimum gradation displaying data voltage has been applied to a gate electrode of the driving transistor satisfy Roff—ILM≧Rbk—Dr.

摘要： Provided is an organic EL display apparatus in which, depending on a situation in which a user uses the organic EL display apparatus, “display with high light use efficiency and high front luminance (luminous efficiency)” or “display with large view angle” is selectable. Pixels each include subpixels having different optical characteristics from each other, and the pixels and the subpixels are respectively arranged in a staggered pattern. Further, the subpixels are independently controlled.

摘要： A dimming method of an organic EL displaying apparatus having a displaying unit constructed by combining pixels each having a substrate, an organic EL element formed over the substrate, a power supply line for supplying a power source to the organic EL element, and at least one TFT provided on a wiring path from the power supply line to the organic EL element. The TFT has a semiconductor layer which is arranged between a source electrode and a drain electrode and is electrically connected to the source electrode and the drain electrode. A laser beam is irradiated from a downward direction of the substrate to a region which does not overlap a gate electrode, the source electrode, the drain electrode, and the wiring layer when seen as a plan view in a plane region where the semiconductor layer is provided.

摘要： A display apparatus includes a plurality of pixels each including first and second organic EL elements whose emitting periods are controlled by respective emitting-period control TFTs. The second organic EL element has a front luminance lower than that of the first organic EL element. An electric charge charged in a storage capacitor as a gradation display signal in a previous frame is erased through an erasing TFT and the second organic EL element.
