Abstract
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.
