The organic el panel, a method of manufacturing a display device using the panel, and an organic organic el el panel

The organic EL panel includes a reflective electrode 3, a transparent electrode 9, the organic light emitting layer 7b, 7g, 7r, and the reflective electrode 3 and disposed on the organic light emitting layer 7b, 7g, a functional layer between 7r. R, G, and B colors of the film thickness of the functional layer is 60nm or less, and is presented with its film thickness of the light emission efficiency value corresponding to the maximum, and the film thickness R, G, and B colors is substantially equal to the functional layer. R, G, B colors of the organic light emitting layer 7b, 7g, 7r optical distance to the reflective electrode 3 is 100nm or less, and R, G, B color optical distance substantially equal.
