PROBLEM TO BE SOLVED: To provide a manufacturing method of an organic EL display device which reduces defective products due to poor formation of a light emitting layer when the light emitting layer is made by an ink-jet process. SOLUTION: In the manufacturing method of an organic EL display device, a material M for forming the light emitting layer where light emitting materials are dissolved in a solvent K is discharged from a nozzle 36 of an ink jet head, at a position corresponding to a pixel 20 arranged on an array substrate 10 to form the light emitting layer 34 on each pixel 20. The poor formation of a light emitting part 20a is detected from the pixel 20 on which the light emitting layer 34 is formed, the solvent K in which the light emitting material is dissolved is discharged on the detected poor formation of the light emitter 20a to dissolve the poor formation of the light emitting layer 34, and then the light emitting layer formation material M is discharged again from the nozzle 36 of the ink jet head to form the light emitting layer 34 on the poor formation of the light emitter 20a again.
