Abstract
The present disclosure relates to a method for manufacturing an EL display apparatus including a light-emitting portion in which a light emitting layer is disposed between a pair of electrodes, a thin film transistor array device for controlling light emission of the light-emitting portion, and an EL display panel in which a plurality of pixels of colors of R, G, and B are disposed. After production of the EL display panel, an inspection step is performed to apply, to each of the pixels, a voltage which is preset for each of the colors of R, G, and B of the pixels, the voltage applied in the inspection step is a potential difference that is a reverse bias voltage opposite to an anode voltage and a cathode voltage during lighting, and the potential difference allows a faulty pixel to turn to a dead dot.
