Abstract:
An active matrix display apparatus includes a substrate having scanning lines, signal lines, and pixels thereon. Each of the pixels includes a sampling transistor for taking in a video signal, a drive transistor for generating a driving current, and a light-emitting device which emits light with luminance in accordance with the video signal. The two-terminal thin-film light-emitting device includes an anode and cathode electrodes, and a light-emitting layer arranged therebetween. At least one of the electrodes is divided into pieces whereby the light-emitting device is divided into sub-light-emitting devices. The sub-light-emitting devices receive the driving current from a driving transistor and emit light with luminance in accordance with the video signal. A sub-light-emitting devices including a short-circuit defect is separated from the corresponding one of the pixels and the driving current is supplied to the remaining sub-light-emitting devices, whereby the luminance in accordance with the video signal is maintained.
