METHOD FOR MANUFACTURING ORGANIC EL DISPLAY DEVICE

摘要

Provided is a method for manufacturing an organic EL display device in which subsequent shorting defects do not occur after electrical repair. In this method for manufacturing an organic EL display device, defective pixels having organic EL elements with shorting defects are specified from among a plurality of light-emitting pixels, and a reverse-bias voltage within a prescribed range is applied to the light-emitting pixels specified as defective pixels. The light emission brightness or pixel current of the light-emitting pixels is measured by applying a prescribed voltage for a fixed period to the light-emitting pixels after completion of the application of the reverse-bias voltage. A separate repair step is performed with respect to the light-emitting pixels in which the amount of change over time of the measured light emission brightness or pixel current is equal to or greater than a threshold value.
