Claim One:
1. A method of manufacturing an organic electroluminescent (EL) display apparatus that includes a display panel having light emitting pixels each of which has a light emitting element, the method comprising: lighting up lighting target pixels set from among the light emitting pixels; causing an imaging device to photograph the display 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 of the lighting target pixels; increasing an amount of luminescence of the undetectable pixel to an amount of luminescence detectable in the detecting of the lighting target pixels, 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 of the lighting target pixels.
