An organic EL display panel including organic light-emission layers formed according to an inkjet method and suppressing decrease in image display quality caused by stripe unevennesses, and a method of manufacturing the same. In a bank layer forming process, openings belonging to a first array and openings belonging to a second array that is adjacent to the first in a row direction are offset with respect to one another in the column direction. In an organic light-emission layer forming process, a head unit is caused to move in a row direction, and nozzles used are switched between the first and second arrays. When a nozzle ejecting an erroneous ink volume is switched between being used and not being used, continuous forming of organic light-emission layers having a same, erroneous film thickness in the row direction is prevented. Thus, unevenness in luminance is suppressed.
