1. A method for making an organic EL display device, wherein the organic EL display device is formed by arranging a plurality of display pixels in a matrix pattern, each display pixel including an organic EL element, the method comprising: dividing a display area into a plurality of predetermined detection areas to selectively cause organic EL elements of a plurality of display pixels in the detection areas to emit light to detect a driving current for each detection area; detecting, based on driving current values detected for respective detection areas, a detection area that has a luminance value different from that of other detection areas and requires correction; calculating correction data required for correcting image data for each pixel that is input to the detection area that requires correction; and storing, in a memory, a position of a pixel that requires correction and related correction data calculated for the pixel.
