Patent ID: 8597067

Claim:
A method of manufacturing an organic electroluminescence (EL) display device which includes pixels, each of which includes an organic EL element, the method comprising: identifying, from among the pixels, a pixel that includes an organic EL element having a short defect as a defective pixel; applying a reverse bias voltage for eliminating the short defect to the pixel identified as the defective pixel in the identifying of the pixel, the reverse bias voltage being within a predetermined range; applying, for a certain period, a voltage having an absolute value that is at most equal to the reverse bias voltage to the pixel to which the reverse bias voltage is already applied in the applying of the reverse bias voltage, and measuring one of a light emission luminance and a pixel current of the pixel in the certain period; again identifying the pixel as the defective pixel that needs to be repaired when a temporal change amount in the one of the light emission luminance and the pixel current measured in the measuring is at least equal to a threshold; and repairing, by using a laser and after the reverse bias voltage is already applied to the pixel, the pixel using a technique different from the technique of applying the reverse bias voltage, the pixel being again identified as the defective pixel.
