A method of manufacturing an organic EL display apparatus including an organic EL panel having light emitting pixels each of which has an organic EL element (OEL) includes: lighting up lighting target pixels set from among the light emitting pixels; causing an imaging device to photograph the organic EL panel and receiving a photographed image from the imaging device; detecting the lighting target pixels using the photographed image; determining whether an undetectable pixel that cannot be detected is included among the lighting target pixels, using a result obtained in the detecting; increasing an amount of luminescence of the undetectable pixel to a detectable amount of luminescence, when it is determined that the undetectable pixel is included; and aligning a relative position of the organic EL display apparatus and the imaging device, using the result obtained in the detecting.

Method of manufacturing organic EL display apparatus, and inspection apparatus

A method of manufacturing an EL display device having a light emitting part, in which a plurality of pixels are arrayed, and a thin-film transistor array device to control light emission of the light emitting part, includes a luminance measurement step of obtaining luminance data of pixel, with the light emitting part being lit. The luminance measurement step includes a first luminance measurement step and a second luminance measurement step. In the first luminance measurement step, a first imaging apparatus obtains luminance data by measuring light emission of the each pixel. The first apparatus has a resolution corresponding to that of the pixels of the light emitting part. In the second luminance measurement step after the first step, a second imaging apparatus measures light emission of a plurality of the pixels to correct the luminance data of the each pixel obtained in the first luminance measurement step. The second imaging apparatus is lower in resolution than the first imaging apparatus.
